MIC4608
600V Half Bridge MOSFET or IGBT Driver General Description Features The MIC4608 is a 600V Half Bridge IGBT or MOSFET
driver. The MIC4608 features a 450ns propagation delay
including a 200ns input filtering time to prevent unwanted
pulses. The low-side and high-side gate drivers are
independently controlled (with shoot thru protection) or
controlled with a single PWM signal. The MIC4608 has
TTL input thresholds. Gate drive supply voltage up to 20V Drives high-side and low-side N-Channel MOSFETs or
IGBTs with independent inputs or with a single PWM
signal ±50V/ns dV/dt immunity TTL input thresholds 200ns input filtering time Shoot thru protection Low power consumption Supply undervoltage protection –40°C to +125°C junction temperature range The robust operation of the MIC4608 ensures that the
outputs are not affected by supply glitches, 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 MIC4608 is available in a 14-pin SOIC package. The
MIC4608 has an operating junction temperature range of
–40°C to +125°C.
