FUNCTION
Charger Bias Supply Input. Bypass DCIN with a 1 μF capacitor to PGND.
Analog Ground
Output Current-Sense Positive Input. Connect a current-sense resistor from CSIP to CSIN.
Output Current-Sense Negative Input
Input Current-Monitor Output. IINP sources the current proportional to the current sensed across
CSSP and CSSN. The transconductance from (CSSP - CSSN) to IINP is 2.8μA/mV. See the Analog
Input Current-Monitor Output section to configure the current monitor for a particular gain setting.
Battery Voltage Feedback Input
AC Detect Output. This open-drain output is high impedance when ACIN is lower than V AA /2.
Connect a 10k pullup resistor from LDO to ACOK .
Input Current Sense for Positive Input. Connect a current-sense resistor from CSSP to CSSN.
Input Current-Sense Negative Input
Dual Mode ? Input for Setting Maximum Charge Current. ISET can be configured either with a
resistor voltage-divider or with a PWM signal from 128Hz to 500kHz. If there is no clock edge
within 20ms, ISET defaults to analog input mode. Pull ISET to GND to shut down the charger. In the
MAX17015A, when the adapter is absent, drive ISET above 1V to enable IINP during battery
discharge. When the adapter is reinserted, ISET must be released to the correct control level within
300ms.
Power Ground Connection for MOSFET Drivers
Low-Side Power-MOSFET Driver Output. Connect to low-side n-channel MOSFET gate.
Linear Regulator Output. LDO provides the power to the MOSFET drivers. LDO is the output of the 5.4V
linear regulator supplied from DCIN. Bypass LDO with a 4.7μF ceramic capacitor from LDO to PGND.
High-Side Driver Supply. Connect a 0.68 μF capacitor from BST to LX.
High-Side Power-MOSFET Driver Output. Connect to high-side n-channel MOSFET gate.
High-Side Driver Source Connection. Connect a 0.68 μF capacitor from BST to LX.
AC Adapter Detect Input. ACIN is the input to an uncommitted comparator.
4.2V Voltage Reference and Device Power-Supply Input. Bypass V AA with a 1μF capacitor to GND.

CC
Voltage Regulation Loop-Compensation Point. Connect 3k
CC to GND.

VCTL
BP
Battery Voltage Adjust Input. VCTL sets the number of cells and adjusts the voltage per cell. The
adjustment range is 4.2V to 4.4V per cell. See the Setting Charge Voltage section .
Backside Paddle. Connect the backside paddle to analog ground.
