ACT2803 PIN DESCRIPTIONS PIN NAME DESCRIPTION 29 LED2 Battery level indicator. 30 LED3 Battery level indicator. 31 LED4 Battery level indicator. 32 LEDLS1 LED1 threshold level shift. Connect a resistor from the pin to AGND to shift LED1 threshold. 33 LEDLS2 LED2 threshold level shift. Connect a resistor from the pin to AGND to shift LED2 threshold. 34 LEDLS3 LED3 threshold level shift. Connect a resistor from the pin to AGND to shift LED3 threshold. 35 LEDLS4 LED4 threshold level shift. Connect a resistor from the pin to AGND to shift LED4 threshold. 36 PT LED indication mode input. The 5 modes of LED indication patterns are set by a voltage at this pin. Connect a resistor at the pin to set the voltage and an LED indication pattern . 37 RIMC RIMC Battery impedance compensation input. Connect a resistor to this pin to offset the LED thresholds in charge mode and discharge mode. 38 HYST The hysteresis window setting input. Connect a resistor at the pin to set the hysteresis windows for LED1, 2, 3, 4. In charge mode, LED thresholds moves up and in discharge mode, LED thresholds moves down. 39 DM Output port auto detection input. Connected to portable device D-. 40 DP Output port auto detection input. Connected to portable device D+. 41 PGND Exposed pad. Must be soldered to ground plane layer(s) on the PCB for best electrical and thermal conductivity. |
