Announcing the launch of an High-side Nch-MOSFET gate driver IC with reverse connection and reverse current protection
～A product which contributes to downsizing and reduced dissipation～
Mar. 6, 2024
Shindengen Electric Manufacturing Co., Ltd. has begun sales of the MF2007SW High-side Nch-MOSFET gate driver IC for reverse connection protection and reverse current protection applications.This product can be used as an ideal diode by being combined with an Nch-MOSFET to contribute to downsizing and reduced dissipation in vehicle device applications.
Can also be used as a bidirectional conduction semiconductor relay by being combined with 2 Nch-MOSFETs to achieve faster responsiveness and reduced size compared to conventional mechanical relays.
■ Overview
Power consumption has increased in automobiles in recent years due to more advanced electronic devices, functional integration, and greater multi-functionality. Conventionally, diodes have been used for reverse connection protection and reverse current protection elements in ECU input parts, however increased dissipation and heat generation from diodes resulting from increased current were impediments to equipment heat dissipation measures and downsizing.There has thus been a growing demand for "ideal diodes" which combine IC and MOSFET to provide rectification while also reducing power dissipation, controlling heat generation, and contributing to downsizing.
Shindengen has launched the MF2007SW High-side Nch-MOSFET gate driver IC in response to these needs. This product can be used as an ideal diode by being combined with an Nch-MOSFET to reduce power dissipation by approximately 72%, and inhibit temperature increases by approximately 51% compared to conventional diodes※1.
This contributes to downsizing and lower power dissipation in equipment which requires reverse connection and reverse current protection, such as automotive products, and output ORing applications.
It can also be used as a bidirectional conduction semiconductor relay※2 by being combined with 2 Nch-MOSFETs to contribute to faster response and downsizing by reducing response time to approximately 1/1000 and mounting area by approximately 96% compared to conventional mechanical relays.
