A MOSFET gate driver switch IPD for automotive high current applications : TPD7106F

2020-05-25 | 반환
Toshiba Electronic Devices & Storage Corporation has launched “TPD7106F”: a gate driver switch IPD[1] that controls conduction and shut-off of current that is supplied for automotive Electronic Control Units (ECUs) such as junction boxes and body control modules.

The new product can form a high-side switch supporting high current application in combination with Toshiba’s automotive low On-resistance N-channel MOSFET[2]. Unlike mechanical relays, the switch does not have contact wear, so it makes devices maintenance-free.

In order to protect MOSFETs in the event of short-circuit, there is an input/output terminal to turn off MOSFETs rapidly, and it can be controlled independently from micro-controllers. It turns MOSFETs off against unusual operation.

Furthermore, it has 150 °C of high operating temperature rating, and enables operating under high temperature environment. The leakage current is suppressed in case of reversed battery connection, and it supports source common connection of MOSFETs. It features low stand-by current, maximum 5 μA.

And it uses small SSOP16[3] package and this contributes to downsizing and low-power-consumption of automotive ECUs.
