The CMS6D181 is a three-phase medium-voltage high-speed gate driver IC designed for bridge circuits using dual N-channel VDMOS power transistors or IGBTs, and can be applied in DC brushless, DC brushed motors, and other application solutions.
The CMS6D181 is a three-phase medium-voltage high-speed gate driver IC designed for bridge circuits using dual N-channel VDMOS power transistors or IGBTs, and can be applied in DC brushless, DC brushed motors, and other application solutions.
The CMS6D181 controls the high-side driver output (HO) and low-side driver output (LO) through input signals (HIN, LIN). The internal 350ns dead-time is the minimum dead-time, and when the microcontroller’s output signal dead-time exceeds the internal dead-time, the actual dead-time will be the value set by the microcontroller. The internal VCC and VBS undervoltage (UVLO) protection functions prevent the system from turning on external power transistors at low drive voltages.
> Floating offset voltage: +600V
> Operating voltage range: 10V~20V
> Internal VCC and VBS undervoltage protection (UVLO)
> Internal shoot-through function to prevent interference
> Internal 350ns dead-time
> High-side and low-side channel matching
> High-side output is in phase with high-side input
> Low-side output is in phase with low-side input
> 3.3V/5V input logic compatibility
> Peak output current: 0.28A at 15V, with a 1nF load, rise time of 75ns
> Peak sink current: 0.52A at 15V, with a 1nF load, fall time of 45ns
