Overview
MIC4609 600V 3-Phase MOSFET/IGBT Driver Features • Gate Drive Supply Voltage up to 20V • Overcurrent Protection with Programmable Restart Delay • 1A Gate Drivers • Dual (HI/LI) Inputs per Phase • Fault Signal Asserts on Overcurrent and VDD UVLO • TTL Input Thresholds • 300 ns Typical Input Filtering Time • Shoot-Through Protection • Low-Power Consumption • Supply Undervoltage Protection • -40°C to +125°C Junction Temperature Range Typical Applications • 3-Phase Motor Drive • Field-Oriented Control (FOC) • White Goods Appliances • Brushless DC Fans General Description The MIC4609 is a 600V 3-phase MOSFET/IGBT driver.
The MIC4609 features a 300 ns typical input filtering time to prevent unwanted pulses and a 550 ns of propagation delay.
The MIC4609 has TTL input thresholds.
The robust operation of the MIC4609 ensures that the outputs are not affected by supply glitches, High Side (HS) ringing below ground, or HS slewing with high-speed voltage transitions.
Undervoltage protection is provided on both the low-side and high-side drivers.
The MIC4609 is available in a 28-pin wide SOIC package.
The MIC4609 has an operating junction temperature range of -40°C to +125°C.
