ABLIC, a group company of MinebeaMitsumi Inc., has released the S-19114 Series of automotive high withstand voltage battery monitoring ICs with the industry’s fastest (*1) voltage detection response.

Mainly, the S-19114 Series battery monitoring IC operates at 36V and features the industry’s fastest detection response time of up to 10μsec (*2). Two components impact the detection response time: the resistance components and the capacitance components in the IC. However, they are not much of a problem as the resistance components of the S-19114 Series are 1/5 of earlier models. Also, the detection response time of capacitance components has been reduced to 1/20 of earlier models.

Additionally, the S-19114 Series have few resistance and capacitance components that impact detection response time. Also, current consumption during operation is a low 2.0µA typ. These make the series ideal for low standby current systems where continuous sensing is required. The S-19114 Series is housed in an ultra-compact package, making it a product that amply meets today’s need for smaller automotive devices.

Major Features

1. Shorter voltage detection response times as well as low current consumption

2. Smaller footprint through ultra-compact HSNT-6(2025) (1.96 × 2.46 × t0.5mm) package

3. The monitoring voltage input pin (SENSE pin) has a wide rated voltage of -30V to 45V

4. Automotive quality

These products have been subjected to the three-temperature test (low, normal and high temperature). According to the AEC (Automotive Electronics Council), this series will comply with AEC-Q100 Grade 0 reliability and quality test defined by the Council. They are also in compliance with the Production Part Approval Process (PPAP).

Also, the new monitoring ICs are designed for voltage detection of automotive batteries and for automotive components, like engines, transmissions, suspensions or ABS, and EV, HEV or PHEV vehicle parts.
