FUNCTION
Charging Voltage Input. Bypass DCIN with a 1μF capacitor to PGND.
Device Power Supply. Output of the 5.4V linear regulator supplied from DCIN. Bypass with a 1μF capacitor to GND.
Source Current-Limit Input. Voltage input for setting the current limit of the input source.
4.096V Voltage Reference. Bypass REF with a 1μF capacitor to GND.
Input-Current Regulation Loop-Compensation Point. Connect a 0.01μF capacitor to GND.
Output-Current Regulation Loop-Compensation Point. Connect a 0.01μF capacitor to GND.
Voltage Regulation Loop-Compensation Point. Connect 1k ? in series with a 0.1μF capacitor to GND.
Shutdown Control Input. Drive SHDN logic low to shut down the MAX1908/MAX8724/MAX8765 MAX8765A.
Use with a thermistor to detect a hot battery and suspend charging.
Charge-Current Monitor Output. ICHG is a scaled-down replica of the charger output current. Use ICHG to
monitor the charging current and detect when the chip changes from constant-current mode to constant-
voltage mode. The transconductance of (CSIP - CSIN) to ICHG is 3μA/mV.
AC Detect Input. Input to an uncommitted comparator. ACIN can be used to detect AC-adapter presence.
AC Detect Output. High-voltage open-drain output is high impedance when V ACIN is less than V REF /2.
Reference Input. Allows the ICTL and VCTL inputs to have ratiometric ranges for increased accuracy.
Output Current-Limit Set Input. ICTL input voltage range is V REFIN /32 to V REFIN . The MAX1908/MAX8724 shut
down if ICTL is forced below V REFIN /100 while the MAX8765/MAX8765A does not. When ICTL is equal to
LDO, the set point for CSIP - CSIN is 45mV.
Analog Ground
Output Voltage-Limit Set Input. VCTL input voltage range is 0 to V REFIN . When VCTL is equal to LDO, the set
point is (4.2 x CELLS)V.
Battery Voltage Input
Cell Count Input. Tri-level input for setting number of cells. GND = 2 cells, open = 3 cells, REFIN = 4 cells.
Output Current-Sense Negative Input
Output Current-Sense Positive Input. Connect a current-sense resistor from CSIP to CSIN.
Power Ground
Low-Side Power MOSFET Driver Output. Connect to low-side nMOS gate.
Low-Side Driver Supply. Bypass DLOV with a 1μF capacitor to GND.
High-Side Power MOSFET Driver Power-Return Connection. Connect to the source of the high-side nMOS.
High-Side Power MOSFET Driver Power-Supply Connection. Connect a 0.1μF capacitor from LX to BST.
High-Side Power MOSFET Driver Output. Connect to high-side nMOS gate.
Input Current-Sense Negative Input
Input Current-Sense Positive Input. Connect a current-sense resistor from CSSP to CSSN.
Input-Current Monitor Output. IINP is a scaled-down replica of the input current. IINP monitors the total
system current. The transconductance of (CSSP - CSSN) to IINP is 3μA/mV.
