constant-voltage Li-Ion battery charger controller. When
combined with a few external components, the TSOT-23
package forms a very small, low cost charger for single
cell lithium-ion batteries. Applications 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 LTC1734 from operating outside …
