MOSFET gate driver switch for intelligent power devices

Toshiba Electronics Europe now offers two new gate driver switch intelligent power devices. Fully AEC-Q100 compliant, the TPD7106F and TPD7107F can be employed to control the conduction and shut-off of currents provided to automotive ECUs, incorporating junction boxes and body control modules. They are also ideal for usage in power distribution modules and semiconductor relays.

When combined with the company's low on-resistance N-channel automotive MOSFETs, such as the TPHR7904PB (40V/150A) or TPH1R104PB (40V/120A), the IPDs can work as high-side switches to control load current. These new solid-state devices can replace mechanical relays, thereby decreasing the size and power consumption of automotive ECUs. As they do not have moving parts, they are free from the contact wear issues connected with mechanical relays, thereby serving to significantly decrease maintenance costs.

The new IPDs reduce BoM costs and component count considerably as they each have a built-in voltage boosting circuit. Efficient operation is ensured with a supply current as low as 5μA (max) for the TPD7106F and 3μA (max.) for the TPD7107F when in stand-by mode. The TPD7106F is provided in a compact 16-pin SSOP package, while the TPD7107F is contained in a WSON10A package. Both function over extensive temperature ranges, with the TPD7107F supporting -40C to +125C and the TPD7106F covering -40C to +150C.
