Connect resistor to ground to set OCP limit. 2 IC Internally connected. Connect this pin to ground. 3 EN Active low enable with internal 200kΩ resistor pull down to GND 4 POK Input supply power-good status pin, open-drain. The POK function is always active whether EN is low or high. Connect a 1kΩ to 100kΩ pull-up resistor to the logic I/O voltage of the host system. 5,6 OUT Output. Connect a 0.1μF~47uF capacitor from OUT to GND. 7,8 IN Power input pin. Connect 1μF capacitor from IN to GND. 9 GND Ground connection. 10 FLT Open-drain output. Active low when input over-voltage, input over-current, battery over-voltage, or over temperature and EN = low. The FLT pin goes to high impedance state when EN = high. Connect a 1kΩ to 100kΩ pull-up resistor to the logic I/O voltage of the host system. 11 BOVP Battery voltage sense input. Connect to battery positive terminal through a 100kΩ resistor to limit the current in case of a short circuit condition. 12 OVP (N/C) Over-voltage protection threshold input (Adjustable only). Fixed version not connected. Pin Configuration TDFN33-12 (Top View) OCP IC EN 1 POK OUT OUT OVP (N/C) BOVP FLT GND IN IN 2 3 4 5 6 12 11 10 9 8 7 |
