4 / 20 page ISL9230 4 FN7642.1 July 22, 2011 13 VIN Power input. The absolute maximum input voltage is 26V. A 4.7µF or larger value capacitor is recommended to be placed very close to the input pin for decoupling purposes. Additional capacitance may be required to provide a stable input voltage. 14 TIME Timing resistor pin. The TIME pin determines the oscillation period by connecting a timing resistor between this pin and GND. The oscillator also provides a time reference for the charger calculated in Equation 2. Equation 3 provides the formula for finding the Pre-conditioning time, which is 1/10 of the Fast Charge timer. Leaving the TIME pin unconnected sets the timer to the default values of 30 minutes for pre-conditioning and 5 hours for fast charge. Where RTIME is in kΩ 15 CONT Active high overrides the end-of-charge (EOC) or timer termination. By pulling the continuous charge CONT pin high, the device will continue to charge the battery when the current has fallen below IEOC or the safety timer has timed out. The status of this pin can not be changed after POR. The CONT pin is internally pulled down to GND by a 280k Ω resistor, but to ensure proper operation, do not leave the CONT pin floating. 16 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 Equation 4: 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. - EPAD Exposed pad. Connect as much copper as possible to this pad either on the component layer or other layers through thermal vias to enhance the thermal performance.
