Stand-Alone, Switch-Mode

Li+ Battery Charger with Internal 28V Switch

General Description

Features

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 1ꢀ0 and a regu-

lated voltage with only a ꢀ.80 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

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.

ꢀ Up to 105A Programmable Charge Cꢂrrent

ꢀ 3±±kHz PWM Osꢄillator ꢁedꢂꢄes Noise

The per-cell battery regulation voltage is set between

4.ꢀV and 4.4V using standard 10 resistors. The num-

ber of cells is set from 1-to-4 by pin strapping. Battery

temperature is monitored by an external thermistor to

prevent charging outside the acceptable temperature

range.

The MAX1758 is available in a space-saving 28-pin

SSOP package. Use the MAX1758EVKIT to help reduce

design time. For a stand-alone charger with a 14V

switch, refer to the MAX1757 data sheet. For a charger

controller capable of up to 4A charging current, refer to

the MAX1737 data sheet.
