AUTOMOTIVE, 105°C OPERATION,
BATTERY MONITORING IC
FOR 3-SERIAL TO 6-SERIAL CELL PACK
Rev.1.0_00
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 in
the purpose, contact to ABLIC Inc. is indispensable.

OUT1 pin: Overcharge and overdischarge detection results
OUT2 pin: Self-test results
Output form is selectable:
CMOS output, Nch open-drain output
Output logic is selectable:
Active "H", active "L"
High-withstand voltage:
Absolute maximum rating 28 V

Lead-free (Sn 100%), halogen-free
AEC-Q100 in process*5
The following documents are available when customers perform verifications for "Hardware Component Qualification"
in order to meet "Functional Safety Requirements".*5, *6
"Hardware Safety Analysis Report"
"Hardware Integration and Testing Report"
"Qualification Kit"
*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.
*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 office for details.
*6. The Non Disclosure Agreement is necessary when providing the documents.
