DC Brushless Motor-Driver - Toshiba
Description
TPD4142K
TOSHIBA Intelligent Power Device High Voltage Monolithic Silicon Power IC
TPD4142K
The TPD4142K is a DC brushless motor driver using high-voltage PWM control.
It is fabricated using a high-voltage SOI process.
The device contains PWM circuit, 3-phase decode circuit, level shift high-side driver, low-side driver, IGBT outputs, FRDs, over-current and under-voltage protection circuits, and a thermal shutdown circuit.
It is easy to control a DC brush less motor by applying a signal from a motor controller and a Hall amp/ Hall IC to the TPD4142K.
Features
