- Part Number:
- MIC4451YM
- Manufacturer:
- Microchip Technology
- Ventron No:
- 3254269-MIC4451YM
- Description:
- IC DRIVER MOSF 12A LO SIDE 8SOIC
- Datasheet:
- MIC4451YM
Description
The MIC4451 and MIC4452 are CMOS MOSFET drivers that are robust, efficient, and easy to use. The MIC4451 is an inverting driver, while the MIC4452 is a non-inverting driver. Both versions are capable of 12A (peak) output and can drive the largest MOSFETs with an improved safe operating margin. The MIC4451/4452 accepts any logic input from 2.4V to Vs without external speed-up capacitors or resistor networks. Proprietary circuits allow the input to swing negative by as much as 5V without damaging the part. Additional circuits protect against damage from electrostatic discharge.
Features
BICMOS/DMOS construction
Latch-up proof: fully-isolated process is inherently immune to any latch-up
Input will withstand negative swing of up to 5V
Matched rise and fall times: 25ns
High peak output current: 12A peak
Wide operating range: 4.5V to 18V
High capacitive load drive: 62,000Pf
Low delay time: 30ns (typ.)
Logic high input for any voltage from 2.4V to Vs
Low supply current 450μA with logic 1 input
Low output impedance: 1.00
Output voltage swing to within 25mV of GND or Vs
Low equivalent input capacitance (typ.): 7pF
Applications
Switch mode power supplies
Motor controls
Pulse transformer driver
Class-D switching amplifiers
Line drivers
Driving MOSFET or IGBT parallel chip modules
Local power ON/OFF switch
Pulse generators
