【Microchip】ATA6847 Series Three-Phase BLDC Motor Drivers
1. Overview:
The ATA6847 is a three-phase brushless motor gate driver system base chip (SBC) designed for brushless motor control, utilising advanced SOI technology. The chip is designed to offer high integration and meet the stringent requirements of modern automotive, industrial and consumer applications. Each gate drive unit (GDU) can be controlled independently via six dedicated parallel inputs; as it integrates two charge pumps for low-side and high-side gate driving, it supports duty cycle operating modes ranging from 0% to 100%.
2. Features:
Three half-bridge drivers for driving external high-side and low-side NMOS MOSFETs:
Independent input control for high-side and low-side NMOS MOSFET gate drivers
Minimum output current: Source > 400 mA, drain > 1.2 A at 12 V
Fixed-output linear regulator:
3.3 V or 5.0 V and 3.3 V (depending on CPN), maximum output current 100 mA
True current foldback
