ACT2804 PIN DESCRIPTIONS PIN NAME DESCRIPTION 1 CSN2 Output current sense negative input for channel 2. 2 CSN1 Output current sense negative input for channel 1. 3 CSP Output current sense positive input. 4, 5 VOUT Power Output Pin. 6, 7 VIN USB or AC Adapter input. 8 OVGATE Output to drive optional external NMOS protect IC from over voltage. 9 OVSENS USB or AC Adapter input sense. 10 SCL I2C clock input. 11 SDA I2C data input. 12 PGND Power ground. Directly connect this pin to IC thermal PAD and connect 10uF or 22uF high quality capacitors from BAT to PGND on the same layer with IC. 13 HSB High side bias pin. Connect a 47nF ceramic capacitor from HSB to SW. 14,15 SW Internal switch connected to a terminal of the output inductor. 16,17 BAT BAT connection. Connect it to battery current sense positive terminal. Bypass BAT pin to PGND pin with high quality ceramic capacitors on the same layer with IC. 18 BATS Battery charge current sense input. Connect to charge sense resistor positive terminal with Kevin sense. 19 BATP Connect to charge sense resistor negative terminal and battery positive terminal. 20 BATC Battery central point connection. Connect to dual battery cell common terminal. 21 CBD Cell balancing discharge. Connect to a discharge resistor from this pin to battery common terminal. 22 BATN Battery negative terminal. 23 ICST Fast charge current setting pin. Connect a resistor from this pin to AGND to set the charging current. The current setting ranges from 0.5A-1.8A. The voltage at this pin reflects the charge current and discharge current in charge mode and discharge mode, respectively. 24 TH Temperature sensing input. Connect to a battery thermistor terminal. 25 VREG + 5V Bias output. Connect a 1.0uF to this pin. This pin supplies up to 50mA output current. The bias turns on in charge mode and discharge mode. Internal register bit can shut down the bias. Bias turns off in HZ mode. |
