The S-19192 Series 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.
In addition, the S-19192 Series can perform a self-test to confirm overcharge and overdischarge detection operations.

Caution: This product can be used in vehicle equipment and in-vehicle equipment. Before using the product for these purposes, it is imperative to contact our sales representatives.

Features

High-accuracy voltage detection circuit for each cell
Overcharge detection voltage n (n = 1 to 6): 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 (n = 1 to 6): 2.300 V to 4.500 V *1
Accuracy ±50 mV
Overdischarge detection voltage n (n = 1 to 6): 1.500 V to 3.000 V (100 mV step)*2, *3
Accuracy ±80 mV
Overdischarge release voltage n (n = 1 to 6): 1.500 V to 3.300 V*4
Accuracy ±100 mV
Self-test results to confirm overcharge and overdischarge detection operations can be output from OUT2 pin.
Delay time shortening during self-test: Available, unavailable
Self-test result output latch: Available, unavailable
 Each delay time is settable by an internal circuit only (External capacitors are not necessary).
Detection delay time: 32 ms, 64 ms, 128 ms, 256 ms
Release delay time: 2.0 ms, 4.0 ms, 8.0 ms, 16.0 ms
Switching control for 3-serial to 6-serial cell is possible by inputting voltage to the SEL1 pin and the SEL2 pin.

This IC has been developed for the battery management system in accordance with ISO 26262. 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 (n = 1 to 6) is selectable from 0 V to 400 mV in 50 mV step.)
*2. Set the voltage difference between the overcharge detection voltage and overdischarge detection voltage to 2.5 V or lower.
Set the voltage ratio so that the following formula is satisfied:
Overcharge detection voltage × 0.7 > Overdischarge detection voltage
*3 When the S-19192 Series is used for monitoring a 3-serial-cell battery, set the overdischarge detection voltage n (n = 1 to 6) to 2.0 V or higher.
*4. Overdischarge release voltage = Overdischarge detection voltage + Overdischarge hysteresis voltage
(Overdischarge hysteresis voltage n (n = 1 to 6) is selectable from 0 V to 0.7 V in 100 mV step.)
*5. Contact our sales representatives for details.
*6. The Non-Disclosure Agreement is necessary when providing the documents.
