42 / 56 page ![]() bq40z50-R1 SLUSCB3 – JULY 2015 www.ti.com 10 Power Supply Recommendations The device manages its supply voltage dynamically according to the operation conditions. Normally, the BAT input is the primary power source to the device. The BAT pin should be connected to the positive termination of the battery stack. The input voltage for the BAT pin ranges from 2.2 V to 26 V. The VCC pin is the secondary power input, which activates when the BAT voltage falls below minimum Vcc. This allows the device to source power from a charger (if present) connected to the PACK pin. The VCC pin should be connected to the common drain of the CHG and DSG FETs. The charger input should be connected to the PACK pin. 42 Submit Documentation Feedback Copyright © 2015, Texas Instruments Incorporated Product Folder Links: bq40z50-R1 |
