FUNCTION
High-Current Charger Input. Connect an AC adapter to INP and IN as close to the device as possible.
INP provides charge current to the battery. INP draws current while the device is in shutdown mode.
Low-Current Charger Input. Bypass IN to GND with a 1μF ceramic capacitor. Connect IN to INP as close
to the device as possible. IN powers the internal LDO and reference. IN draws current while the device is
in shutdown mode.
Ground. Connect the exposed paddle to GND.
Current-Sense Transconductance Amplifier Output. Connect a resistor from SETI to GND to program the
maximum charge current and to monitor the actual charge current. SETI pulls to GND during shutdown.
Linear Regulator Output. Connect CHGEN , TEMP, TMAX, FULLI, and MODE to VL to program logic high.
VL discharges to GND during shutdown.
Maximum Charging-Time Select Input (MAX1501 Only). TMAX sets the maximum charging time. Connect
TMAX to GND to set the maximum charging time to 3 hours. Leave TMAX floating to set the maximum
charging time to 4.5 hours. Connect TMAX to VL to set the maximum charging time to 6 hours. TMAX
pulls to GND through a 50k ? resistor in shutdown.
Internally Connected in the MAX1501Z. Leave floating.
Top-Off-Current Select Input. FULLI sets the end-of-charge threshold as a percentage of the fast-charge
current. Connect FULLI to GND to set the end-of-charge threshold to 10% of the fast-charge current.
Connect FULLI to VL to set the end-of-charge threshold to 20% of the fast-charge current. Leave FULLI
floating to set the end-of-charge threshold to 30% of the fast-charge current. FULLI pulls to GND through
a 50k ? resistor in shutdown.
Die Temperature Select Input. TEMP sets the die temperature regulation point for the thermal-control
loop. Connect TEMP to GND to regulate the die temperature at +95 ° C. Leave TEMP floating to regulate
the die temperature at +115 ° C. Connect TEMP to VL to regulate the die temperature at +135 ° C. TEMP
pulls to GND through a 50k ? resistor in shutdown.
Mode Select Input. MODE and CHGEN together control charging functions (Table 1). An internal 175k ?
pulldown resistor pulls MODE low.
Charge Enable Input. CHGEN and MODE together control charging functions (Table 1). An internal
175k ? pulldown resistor pulls CHGEN low.
Input Voltage Range Indicator. The open-drain ACOK output asserts low when 4.2V ≤ V IN ≤ 6.25V and
V IN - V BATT ≥ 100mV. ACOK requires an external 100k ? pullup resistor. ACOK floats in shutdown.
Battery Connection. Connect the positive terminal of the battery to BATT. BATT draws less than 5μA
during shutdown.
Battery Voltage Selection Input. SELV sets the battery regulation voltage in Li+ and NiMH/NiCd modes
(Table 2). For no-battery mode, the battery voltage defaults to 4.0V. An internal 175k ? resistor to VL pulls
SELV high.
Battery Charging Indicator. Connect the anode of a red LED to IN and the cathode to RLED . RLED
asserts low when the input supply is present and the battery is charging, regardless of cell chemistry.
RLED sinks 10mA. RLED goes high impedance in shutdown. Connect a pullup resistor to the μP’s I/O
supply when interfacing with a μP logic input.
Full-Charge Indicator. Connect the anode of a green LED to IN and the cathode to GLED . GLED asserts
low when the input supply is present and the battery has reached the top-off current threshold set by
FULLI, regardless of cell chemistry. GLED sinks 20mA. GLED goes high impedance in shutdown.
Connect a pullup resistor to the μP’s I/O supply when interfacing with a μP logic input.
