Pin Descriptions
VIN -
Power input. The absolute maximum input voltage is
28V. A 0.47
μ
F 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
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 R
IMIN
is in k
. 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 R
IREF
is in k
. 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
μ
F 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.
