MAX1737
Stand-Alone Switch-Mode
Lithium-Ion Battery-Charger Controller
General Description
The MAX1737 is a switch-mode lithium-ion (Li+) battery
charger that charges one to four cells. It provides a
regulated charging current and a regulated voltage
with only a ±0.8% total voltage error at the battery ter-
minals. The external N-channel switch and synchronous
rectifier provide high efficiency over a wide input volt-
age range. A built-in safety timer automatically termi-
nates charging once the adjustable time limit has been
reached.
The MAX1737 regulates the voltage set point and charg-
ing current using two loops that work together to transi-
tion smoothly between voltage and current regulation. An
additional control loop monitors the total current drawn
from the input source to prevent overload of the input
supply, allowing the use of a low-cost wall adapter.
The per-cell battery voltage regulation limit is set
between +4.0V and +4.4V and can be set from one to
four by pin strapping. Battery temperature is monitored
by an external thermistor to prevent charging if the bat-
