Small size and low On-resistance
P-channel MOSFET for automotive equipment: SSM3J374R, etc.

Product News 2017-08

SOT-23F, SOT-323F (UFM), SOT-346 (S-Mini).

The ten products, including “SSM3J374R”, are small, low On-resistance P-channel MOSFETs for automotive devices.
Three types of small and surface mounting packages have been prepared: SOT-23F and SOT-323F (Toshibaʼs package name: UFM), and SOT-346 (S-Mini). Many of the new products have low On-resistance characteristics and support 1.5 V drive, so that lower voltage of BMS[1] control ICs can be supported. In addition, all the products are qualified for AEC-Q101.
In order to increase the cruising range of electric vehicles such as EVs and HEVs[2], cell capacity is becoming larger, and current to balance cells is also increasing. In conventional ICs with embedded cell balance circuit, the chip temperature can easily increase while operating. We propose circuit design that suppresses the increase in chip temperature by external our low voltage drive MOSFET for the cell balancing purpose.

Features

  • Three kinds of small and surface mounting packages
  • 1.5 V low voltage drive (Not for SSM3J374R and SSM3J372R)
  • AEC-Q101 qualified

Applications

Automotive equipment

  • Battery cell balance circuit
  • Load switch circuit
