MIC4604中文资料85V 1 A Half Bridge MOSFET Gate Drivers with Programmable Gate Drive数据手册Microchip规格书

描述 Description

The MIC4604 is an 85 V 1 A Half Bridge MOSFET gate driver. The MIC4604 features fast 39 ns propagation delay times and 20 ns driver rise/fall times for a 1 nF capacitive load. The low-side and high-side gate drivers are independently controlled. The MIC4604 has TTL input thresholds. It includes a high-voltage internal diode that helps charge the high-side gate drive bootstrap capacitor. A robust, high-speed, and low-power level shifter provides clean level transitions to the high-side output. The robust operation of the MIC4604 ensures that the outputs are not affected by supply glitches, HS ringing below ground, or HS slewing with high-speed voltage transitions. Under voltage protection is provided on both the low-side and high-side drivers. The MIC4604 is available in an 8-pin SOIC package and a tiny 10-pin 2.5 × 2.5 mm TDFN package. Both packages have an operating junction temperature range of -40°C to +125°C.
