  • Toshiba’s latest offering aims to control the conduction and shut-off of the current supplied to automotive electronic control units (ECUs)
  • Includes self-protection and built-in diagnostic functions

Toshiba Electronic Devices has launched the TPD7107F, a gate driver switch Intelligent Power Device (IPD) that can control the conduction and shut-off of the current supplied to automotive electronic control units (ECUs), such as junction boxes and body control modules.

Integrated with Toshiba’s automotive low On-resistance N-channel MOSFET TPHR7904PB/ TPH1R104PB, the TPD7107F forms a high-side switch that is suitable for the load current. As an electronic switch, free from the contact wear of mechanical relays, the new IPD can help to reduce the size and power consumption of automotive ECUs, thus making them maintenance-free.

By delivering enhanced functions that support the high reliability required for automotive ECU (self-protection and built-in diagnostic functions), the new IPD monitors load operation and the MOSFET to which it is connected. In abnormal operation, it rapidly turns off the MOSFET for reducing the load on the MOSFET. The new IPD reduces peripherals such as capacitors since it has built-in a voltage boosting circuit and secures supply current as low as 3μA (max.) during stand-by.

Additional Features

  • Supply voltage  VDD (at t≤400ms): -36 V to +36 V ; (at @t≤20ms): -20 V to +20 V
  • Power dissipation, PD: 1.84 W
  • Operating temperature, Topr : 40 degree Celsius to +125 degree Celsius

TPD7107F is AEC-Q100 qualified and housed in a WSON10A package.
