DescripTion
The
LTC
®
1734
is a low cost, single cell, constant-current/
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.
The LTC1734 is available in 4.1V and 4.2V versions with
1% accuracy. Constant current is programmed using a
single external resistor between the PROG pin and ground.
Manual shutdown is accomplished by floating the program
resistor while removing input power automatically puts
the LTC1734 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 LTC1734 from operating outside
of safe limits. No external blocking diode is required.
The LTC1734 can also function as a general purpose current
source or as a current source for charging nickel-cadmium
(NiCd) and nickel-metal-hydride (NiMH) batteries using
external termination.

jishuaihu Talking
I am interested in single chip microcomputers, and I have figured out a temperature alarm. If I have any questions, please help me.
I just started learning microcontrollers. This is my first time to make a simple temperature alarm based on the examples in the book. There was a problem when linking. The main program is as follows: ...
