Series: -
Function: Charge Management
Battery Chemistry: Lithium-Ion (Li-Ion)
Packaging: Tube
Operating Temperature: -30°C ~ 85°C
Mounting Type: Through Hole
Manufacturer: Rohm Semiconductor
Voltage - Supply: 10 V ~ 20 V
Package / Case: 12-SIP + Tab
Supplier Device Package: 12-HSIP-B
Features: 1) Output voltage can be varied using an external resistor.
2) The output pin is PNP output with low saturation voltage.
3) Built-in output current limiting circuit protects batteries
from excessive current, and prevents destruction
of the IC due to output shorts.
The initial charge current is set to a low value (the current
limit pin voltage can be used to vary the current limit value).
4) Pulse charging at over 99% of the final voltage.
5) Built-in over-discharge battery return circuit.
6) Built-in charge fault protection circuit.
7) Built-in over-voltage battery operation circuit.
8) Built-in LED output for charge display (two outputs).
9) 12-pin power package provides large power dissipation in a compact package.
10) Temperature protection circuit prevents thermal destruction of the IC.ApplicationLithium-ion (two cell) battery chargers, and charging circuitsSpecifications
