NCD83591 – 3 Phase, 60V Gate Drover for Motor Control Applications
The NCD83591 is an easy-to-use, 60V multi−purpose 3−phase gate driver with a high gain-bandwidth current sense amplifier, making it ideal for trapezoidal motor control applications. It includes a configurable constant gate drive source current of 5 to 250mA on the high side, which is a 2 times proportional sink current on the low side. The High Side Gate drive is enabled with an embedded charge pump that allows for dc static drive and is tolerant to -12V DC. The gate driver is packaged in a small footprint QFN28 (4x4) and with a high level of integration, making it ideal to optimize the overall BOM cost.
Features:
- 5V to 60V operational supply voltage with abs max of 70V
- Constant current drive of power FET up to 250mA
- Internally generated gate drive supply voltages
- Gate sensing for external FET shoot-through protection
- Embedded high GBW general purpose amplifier with external configurable gain
- Embedded charge pump function allowing DC static drive
- Integrated Protection Features
- Internal gate pull-down to GND during loss of VDD (core) power
- Under voltage lock out on VM, VGL, and VGH-VM
- 4kV HBM and 1kV CDM ESD protection
