NAME A1 VLDO1 O Output voltage of LDO1 A2 HOLD_LDO1 I Power-on input for LDO1. When pulled HIGH, LDO1 is kept enabled after PB_IN was released HIGH. A3 GPIO3 I/O General purpose I/O or 5-mA current sink A4 GPIO1 I/O General purpose I/O A5 SCLK I Clock input for the I 2C interface B1 VINLDO1 I Input voltage for LDO1 B2 GND — Connect to AGND and PGND B3 GPIO2 I/O General purpose I/O or 5-mA current sink B4 GPIO0 I/O General purpose I/O B5 SDAT I/O Data line for the I 2C interface C1 AGND — Analog ground C2 TS I Connect a thermistor from this pin to GND for battery temperature C3 INT O Open-drain interrupt output C4 PB_IN I Push button input; Turns on DCDC1 and LDO1 if pulled to GND. Open-drain output of the reset generator; This output goes active LOW when the output voltage of LDO1 falls 8% below its target C5 RESET O voltage. D1 FB_DCDC1 I Feedback input of step-down converter D2 HOLD_DCDC1 I Power-On input for DCDC1 converter. When pulled HIGH, the DC-DC converter is kept enabled after PB_IN was released HIGH. D3 BAT I/O Connect to battery + terminal D4 SYS O System voltage; output of the power path manager. Power input for step-down converter DCDC1 D5 ISET I Connect a resistor from this pin to GND to set fast charge current E1 PGND — Power ground E2 L1 O Switch output of step-down converter E3 BAT I/O Connect to battery + terminal E4 SYS O System voltage; output of the power path manager. Power input for step-down converter DCDC1 E5 AC I Input power for power manager, connect to external DC supply. 4 Submit Documentation Feedback Copyright © 2009–2015, Texas Instruments Incorporated Product Folder Links: TPS65720 TPS657201 TPS657202 TPS65721 |
