Lithium-Ion Linear
Battery Charger in ThinSOT
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.
