■NOTES ON USE
1. For temporary, transitional voltage drop or voltage rising phenomenon, the IC is liable to malfunction should the ratings be exceeded.
2. Where wiring impedance is high, operations may become unstable. Please strengthen V
IN
and BAT wiring in particular.
3. Please wire the C
IN
, C
L
and charge current setting resistor to the IC as close as possible.
4. Do not connect anything other than a resistance for setting the charge current to the I
SET
pin.
5. Torex places an importance on improving our products and their reliability. We request that users incorporate fail-safe designs and
post-aging protection treatment when using Torex products in their systems.
6. This IC uses an external thermistor to detect and control temperature with high accuracy. Please sufficiently test the position of the
external thermistor to ensure that it enables accurate temperature detection.
7. Reversing the polarity of the battery may cause destruction and is extremely dangerous. Never reverse the polarity of the battery.
8. Short-circuiting to neighboring pins may cause malfunctioning and destruction. Exercise sufficient caution when mounting and using
the IC.
9. If a large ripple voltage occurs at the V
IN
pin, the IC may malfunction. Please test thoroughly.
10. Taking the temperature characteristics and the dispersion into consideration, please set the charge current not to exceed the range of
200mA to 800mA.
11. If the I
SET
pin is shorted to the GND, there is a possibility that the IC is destroyed before the over-current monitor function is activated.
12. When V
BAT
is 1V or less, the error range of the trickle charge current becomes big. When V
IN
– V
BAT
voltage is high in particular, please
pay attention when using as there are possibilities that a large trickle current flows.
13. In case that the impedance between BAT pin and Li-ion battery is high at the CV charging under the low temperature, there are
possibilities that V
BAT
oscillates and charge error takes place, so please place the Li-ion battery as close to the IC as possible.
