MAX1758
Stand-Alone, Switch-Mode
Li+ Battery Charger with Internal 28V Switch
General Description
The MAX1758 is a switch-mode lithium-ion (Li+) battery
charger that charges one-to-four cells. It provides a reg-
ulated charging current accurate to ±10% and a regu-
lated voltage with only a ±0.8% total voltage error at the
battery terminals. The internal high-side switch delivers
a programmable current of up to 1.5A to charge the bat-
tery. The built-in safety timer automatically terminates
Features
o Stand-Alone Charger for Up to 4 Li+ Batteries
o ±0.8% Battery Regulation Voltage Accuracy
o Low-Dropout 98% Duty Cycle
o Safely Precharges Near-Dead Cells
o Continuous Voltage and Temperature Monitoring
charging once the adjustable time limit has been
reached.
The MAX1758 regulates the voltage set point and
charging current using two loops that work together to

transition smoothly between voltage and current regula-
tion. An additional control loop monitors the total cur-
rent drawn from the input source (charging + system),
and automatically reduces battery-charging current,
preventing overload of the input supply and allowing
the use of a low-cost wall adapter.
The per-cell battery regulation voltage is set between
4.0V and 4.4V using standard 1% resistors. The num-
ber of cells is set from 1-to-4 by pin strapping. Battery
o Safety Timer Prevents Overcharging
o Input Current Limiting
o Space-Saving 28-Pin SSOP
o 300kHz PWM Oscillator Reduces Noise
Ordering Information
temperature is monitored by an external thermistor to
prevent charging outside the acceptable temperature
