5 / 10 page 5 FN9207.0 October 4, 2005 Pin Descriptions VIN - Power input. The absolute maximum input voltage is 28V. A 0.47 µF or larger value X5R ceramic capacitor is recommended to be placed very close to the input pin for decoupling purpose. Additional capacitance may be required to provide a stable input voltage. PPR - Open-drain power presence indication. The open- drain MOSFET turns on when the input voltage is above the POR threshold but below the OVP threshold and off otherwise. This pin is capable to sink 10mA (minimum) current to drive a LED. The maximum voltage rating for this pin is 7V. This pin is independent on the EN-pin input. CHG - Open-drain charge indication pin. This pin outputs a logic LOW when a charge cycle starts and turns to HIGH when the end-of-charge (EOC) condition is qualified. This pin is capable to sink 10mA min. current to drive an LED. When the charger is disabled, the CHG outputs high impedance. EN - Enable input. This is a logic input pin to disable or enable the charger. Drive to HIGH to disable the charger. When this pin is driven to LOW or left floating, the charger is enabled. This pin has an internal 200k Ω pull-down resistor. GND - System ground. IMIN - End-of-charge (EOC) current program pin. Connect a resistor between this pin and the GND pin to set the EOC current. The EOC current IMIN can be programmed by the following equation: Where RIMIN is in kΩ. The programmable range covers 5% (or 10mA, whichever is higher) to 50% of IREF. When programmed to less than 5% or 10mA, the stability is not guaranteed. IREF - Charge-current program and monitoring pin. Connect a resistor between this pin and the GND pin to set the charge current limit determined by the following equation: Where RIREF is in kΩ. The IREF pin voltage also monitors the actual charge current during the entire charge cycle, including the trickle, constant-current, and constant-voltage phases. When disabled, VIREF = 0V. BAT - Charger output pin. Connect this pin to the battery. A 1 µF or larger X5R ceramic capacitor is recommended for decoupling and stability purposes. When the EN pin is pulled to logic HIGH, the BAT output is disabled. EPAD - Exposed pad. Connect as much as possible copper to this pad either on the component layer or other layers through thermal vias to enhance the thermal performance.
