Power MOSFET gate driver IPD for automotive three-phase brushless motors that helps reduce mounting size : TPD7212FN

2020-08-31 | 返回

Toshiba Electronic Devices & Storage Corporation has launched “TPD7212FN” : Intelligent Power Device (IPD) which is a power MOSFET gate driver for automotive three-phase brushless motors.

The new product “TPD7212FN” uses our latest process BiCD for integrating various analog devices and SSOP30 package[1]. Its package size was miniaturized from the conventional product “TPD7210F”[2]. The mounting area of the package is about 71 % and the height is about 80 % of the conventional product, and the pitch between pins is typical 0.65 mm. Thereby, mounting size is reduced. And it has a built-in charge pump circuit for high side N-channel power MOSFET drive, allowing a three-phase full bridge circuit to be formed easily.
The new product has extended various protection and diagnosis features, allowing it to provide feedback to systems. And it supports a wide operating temperature range (-40 °C to 150 °C) to be easily used for automotive equipment. In addition, it offers reliability conforming to AEC-Q100.

Notes :
[1] SSOP30 package : 9.7×7.6×1.2 mm (typ.)
[2] SSOP24 package : 13.0×8.0×1.5 mm (typ.)

Features
> Capable of driving the gates of power MOSFETs for three-phase brushless motors (six outputs built in)
> Built-in diagnosis features for driver power source and output terminal voltages
> AEC-Q100 qualified

Applications
Motor drivers for automotive
> Oil pumps, water pumps
> Fan motors
> Electric turbochargers
