Product Overview
HTSSOP-16 (FR016-A)This IC is a monitoring IC for automotive rechargeable batteries, which includes high-accuracy voltage detection circuits and delay circuits. Switching control for 3-serial to 6-serial cell is possible by inputting voltage to the SEL1 pin and the SEL2 pin. By cascade connection, it is possible to protect 7-serial or more cells lithium-ion rechargeable battery pack. In addition, this IC can perform a self-test to confirm overcharge and overdischarge detection operations.
Features
- High-accuracy voltage detection circuit for each cell
- Overcharge detection voltage n: 2.500 V to 4.500 V (25 mV step)
Accuracy ±20 mV (Ta = +25°C)
Accuracy ±30 mV (Ta = -5°C to +55°C) - Overcharge release voltage n: 2.300 V to 4.500 V*1
Accuracy ±50 mV - Overdischarge detection voltage n: 1.000 V to 3.000 V (100 mV step)*2
Accuracy ±80 mV - Overdischarge release voltage n: 1.000 V to 3.300 V*3
Accuracy ±100 mV - Self-test results to confirm overcharge and overdischarge detection operations can be output from the OUT1 pin and the OUT2 pin.
- Cascade connection function:
- Battery voltage monitoring of multiple modules is possible by connecting the upper module output to the CASI1 pin and the CASI2 pin.

ABLIC Inc. can provide a safety manual for this IC.*5, *6
*1. Overcharge release voltage = Overcharge detection voltage − Overcharge hysteresis voltage
(Overcharge hysteresis voltage n is selectable from 0 V to 400 mV in 50 mV step.) *2. When this IC is used for monitoring a 3-serial-cell battery, set the overdischarge detection voltage n to 1.6 V or higher. *3. Overdischarge release voltage = Overdischarge detection voltage + Overdischarge hysteresis voltage
(Overdischarge hysteresis voltage n is selectable from 0 V to 0.7 V in 100 mV step.) *4. Set the delay time to detection delay time > release delay time. *5. Contact our sales representatives for details. *6. A Non-Disclosure Agreement is necessary when providing the documents.
