NOTES:
Pin Descriptions
VIN - Power input. The absolute maximum input voltage is
28V. A 1µF 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 an LED. The maximum voltage rating for this
pin is 7V. This pin is independent on the EN-pin input.
JIGON - Output pin of the auxiliary 2-input OR gate. One of
the inputs is internal and is connected to the inverted PPR
logic. The other input is from the JIGIN pin driven externally
to provide system booting enable signal.
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 200kΩ pull-down resistor.

3. The output is used to test the VOS threshold. The output current will toggle between 0 and the CC current when VOS crosses over the threshold.
4. For junction temperature below +100°C.
5. The charge current can be affected by the thermal foldback function if the IC under the test setup cannot dissipate the heat.

GND - System ground.
JIGIN - One of the inputs of the 2-input auxiliary OR gate.
There is a 240kΩ pull down resistor at this pin.
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 1:
Where R
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
1µF 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 copper as possible
to this pad either on the component layer or other layers
through thermal vias to enhance the thermal performance.
