L99PM60S Power management system IC Features One 5 V low-drop voltage regulators (100 mA, continuous mode) Low standby current: VBAT-standby, 7 A; V1-standby, 45 A Window watchdog and fail-safe functionality Configurable fail safe output Programmable reset threshold (4.6 V, 3.5 V) VS monitoring / temperature measurement LIN 2.1 compliant (SAEJ2602 compatible) transceiver High-speed LIN Flash mode up to 100 kbit/s ST SPI interface for mode control and diagnostic 2 high-side drivers for e.g. LED or HALL (RDSon,typ = 7 ) 2 relay drivers ( RDSon,typ = 2 ) Outputs are short-circuit protected Direct drive feature for high-sides Temperature warning and thermal shutdown Table 1. PowerSSO-16 SO-16 Applications Automotive ECU such as door zone and body control modules. Description The L99PM60S is a power management system IC containing one low-drop regulator direct drive feature for high-side drivers and LIN 2.1 compliant SAEJ602 transceiver. The integrated standard serial peripheral interface (SPI) controls all L99PM60S operation modes and provides driver diagnostic functions.
