The LTC

1734L is a low cost, single cell, constant-current/

constant-voltage Li-Ion battery charger controller. When

combined with a few external components, the SOT-23

package forms a very small, low cost charger for single cell

lithium-ion batteries. The LTC1734L is a lower charge

current version of the LTC1734.

The LTC1734L provides a fixed float voltage of 4.2V with

1% accuracy (for 4.1V and 4.15V float voltages, contact

LTC Marketing). Constant current is programmed using a

single external resistor between the PROG pin and ground.

Manual shutdown is accomplished by floating the pro-

gram resistor while removing input power automatically

puts the LTC1734L into a sleep mode. Both the shutdown

and sleep modes drain near zero current from the battery.

Charge current can be monitored via the voltage on the

PROG pin allowing a microcontroller or ADC to read the

current and determine when to terminate the charge cycle.

The output driver is both current limited and thermally

protected to prevent the LTC1734L from operating outside

of safe limits. No external blocking diode is required.

The LTC1734L can also function as a general purpose

current source or as a current source for charging nickel-

cadmium (NiCd) and nickel-metal-hydride (NiMH) batter-

ies using external termination.
