MIC4607
85V, Three-Phase MOSFET Driver with Adaptive
Dead-Time, Anti-Shoot-Through and Overcurrent
Protection
Features General Description • Gate Drive Supply Voltage Up To 16V
• Overcurrent Protection
• Drives High-Side And Low-Side N-Channel
MOSFETs With Independent Inputs Or With A
Single PWM Signal
• TTL Input Thresholds
• On-Chip Bootstrap Diodes
• Fast 35 ns Propagation Times
• Shoot-Through Protection
• Drives 1000 pF Load With 20 ns Rise And Fall
Times
• Low Power Consumption
• Supply Undervoltage Protection
• –40°C to +125°C Junction Temperature Range The MIC4607 is an 85V, three-phase MOSFET driver.
The MIC4607 features a fast (35 ns) propagation delay
time and a 20 ns driver rise/fall time for a 1 nF
capacitive load. TTL inputs can be separate high-and
low-side signals or a single PWM input with high and
low drive generated internally. High-and low-side
outputs are guaranteed to not overlap in either mode.
The MIC4607 includes overcurrent protection as well
as a high-voltage internal diode that charges the
high-side gate drive bootstrap capacitor. Applications
• Three-Phase and BLDC Motor Drives
• Three-Phase Inverters A robust, high-speed, and low-power level shifter
provides clean level transitions to the high-side output.
The robust operation of the MIC4607 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 MIC4607 is available in a both a 28-pin 4 mm ×
5 mm QFN and 28-pin TSSOP package with an
operating junction temperature range of –40°C to
+125°C. Typical Application Circuit
