Overvoltage is detected by comparing the actual cell voltage to a protection voltage reference, VOV. If any cell voltage exceeds the programmed OV value, a timer circuit is activated. When the timer expires, the OUT pin goes from inactive to active state. Cell Voltage (V) (V5-V4, V4-V3, V 3-V2, V2-V1, V1-VSS) For NCH Open Drain Active Low configurations, the OUT pin pulls down to VSS when active (OV present) and is high impedance when inactive (no OV).

To enter CTM, VDD should be set to at least 10 V higher than V5 (see Figure 12). The delay timer is greater than 10 ms, but considerably shorter than the timer delay in normal operation. To exit Customer Test Mode, remove the VDD to a V5 voltage differential of 10 V so that the decrease in this value automatically causes an exit. 12 Submit Documentation Feedback Copyright (c) 2012-2014, Texas Instruments Incorporated Product Folder Links: bq771800 bq771801 bq771802 bq771803 bq771807 bq771808 bq771809 bq771815 bq771800, bq771801, bq771802 bq771803, bq771807, bq771808 bq771809, bq771815 www.ti.com SLUSAX1D - DECEMBER 2012 - REVISED NOVEMBER 2014 Customer Test Mode (continued) CAUTION Avoid exceeding any Absolute Maximum Voltages on any pins when placing the part into Customer Test Mode.
