1 General description

The 33772 is a SMARTMOS lithium-ion battery cell controller IC designed for automotive

applications, such as hybrid electric (HEV) and electric vehicles (EV) along with industrial

applications, such as energy storage systems (ESS) and uninterruptible power supply

(UPS) systems.

The device performs ADC conversions of the differential cell voltages and current, as well

as battery coulomb counting and battery temperature measurements. The information is

digitally transmitted through the Serial Peripheral Interface (SPI) or Transformer Isolation

(TPL) to a microcontroller for processing.

POR with VPWR rising:

5.6 V ≤ VPWR < 6.0 V (SPI)

6.6 V ≤ VPWR < 7.0 V (TPL)

6.0 V ≤ VPWR ≤ 30 V (SPI)

7.0 V ≤ VPWR ≤ 30 V (TPL)

In both upper and lower limited operating range, no information can be provided about IC

performance. Only the detection of VPWR overvoltage is guaranteed in the upper limited

operating range.

(MC33xxxD enter 33xxx), and review parametrics.

[3] Thermal resistance between the die and the printed circuit board per JEDEC JESD51-8. Board temperature is measured on the top surface of the board

near the package.

[4] Junction temperature is a function of die size, on-chip power dissipation, package thermal resistance, mounting site (board) temperature, ambient

temperature, air flow, power dissipation of other components on the board, and board thermal resistance.

[5] Per JEDEC JESD51-6 with the board (JESD51-7) horizontal.

[6] Thermal resistance between the die and the case top surface as measured by the cold plate method (MIL SPEC-883 Method 1012.1), with the cold plate

temperature used for the case temperature.

[7] Thermal resistance between the die and the solder pad on the bottom of the package based on simulation without any interface resistance.

[8] Thermal characterization parameter indicating the temperature difference between the package top and the junction temperature per JEDEC JESD51-2.

When Greek letter (Ψ) is not available, the thermal characterization parameter is written as Psi-JT.

Short data sheet — A short data sheet is an extract from a full data sheet

with the same product type number(s) and title. A short data sheet is

intended for quick reference only and should not be relied upon to contain

detailed and full information. For detailed and full information see the

relevant full data sheet, which is available on request via the local NXP

Semiconductors sales office. In case of any inconsistency or conflict with the

short data sheet, the full data sheet shall prevail.

Product specification — The information and data provided in a

technical data data sheet shall define the specification of the product as

agreed between NXP Semiconductors and its customer, unless NXP

Semiconductors and customer have explicitly agreed otherwise in writing.

In no event however, shall an agreement be valid in which the NXP

Semiconductors product is deemed to offer functions and qualities beyond

those described in the technical data data sheet.

10.3 Disclaimers

Limited warranty and liability — Information in this document is believed

to be accurate and reliable. However, NXP Semiconductors does not

give any representations or warranties, expressed or implied, as to the

accuracy or completeness of such information and shall have no liability

of any products or rework charges) whether or not such damages are based

on tort (including negligence), warranty, breach of contract or any other

legal theory. Notwithstanding any damages that customer might incur for

any reason whatsoever, NXP Semiconductors’ aggregate and cumulative

liability towards customer for the products described herein shall be limited

in accordance with the Terms and conditions of commercial sale of NXP

Semiconductors.

Right to make changes — NXP Semiconductors reserves the right to

make changes to information published in this document, including without

limitation specifications and product descriptions, at any time and without

notice. This document supersedes and replaces all information supplied prior

to the publication hereof.

Applications — Applications that are described herein for any of these

products are for illustrative purposes only. NXP Semiconductors makes

no representation or warranty that such applications will be suitable

for the specified use without further testing or modification. Customers

are responsible for the design and operation of their applications and

products using NXP Semiconductors products, and NXP Semiconductors

accepts no liability for any assistance with applications or customer product

design. It is customer’s sole responsibility to determine whether the NXP

Semiconductors product is suitable and fit for the customer’s applications

and products planned, as well as for the planned application and use of

customer’s third party customer(s). Customers should provide appropriate

design and operating safeguards to minimize the risks associated with

their applications and products. NXP Semiconductors does not accept any

liability related to any default, damage, costs or problem which is based

on any weakness or default in the customer’s applications or products, or

the application or use by customer’s third party customer(s). Customer is

responsible for doing all necessary testing for the customer’s applications

and products using NXP Semiconductors products in order to avoid a

default of the applications and the products or of the application or use by

customer’s third party customer(s). NXP does not accept any liability in this

respect.

Limiting values — Stress above one or more limiting values (as defined in

the Absolute Maximum Ratings System of IEC 60134) will cause permanent

damage to the device. Limiting values are stress ratings only and (proper)

operation of the device at these or any other conditions above those

given in the Recommended operating conditions section (if present) or the

Characteristics sections of this document is not warranted. Constant or

repeated exposure to limiting values will permanently and irreversibly affect

the quality and reliability of the device.

Terms and conditions of commercial sale — NXP Semiconductors

products are sold subject to the general terms and conditions of commercial

sale, as published at http://www.nxp.com/profile/terms, unless otherwise

agreed in a valid written individual agreement. In case an individual

agreement is concluded only the terms and conditions of the respective

agreement shall apply. NXP Semiconductors hereby expressly objects to

applying the customer’s general terms and conditions with regard to the

purchase of NXP Semiconductors products by customer.

Suitability for use in automotive applications — This NXP

Semiconductors product has been qualified for use in automotive

applications. Unless otherwise agreed in writing, the product is not designed,

authorized or warranted to be suitable for use in life support, life-critical or

safety-critical systems or equipment, nor in applications where failure or
