TC4420M/TC4429M

6A High-Speed MOSFET Drivers

General Description

Features

• Latch-Up Protected: Will Withstand >1.5A

Reverse Output Current

The TC4420M/TC4429M are 6A (peak), single-output

MOSFET drivers. The TC4429M is an inverting driver

(pin-compatible with the TC429M), while the TC4420M

is a non-inverting driver. These drivers are fabricated in

CMOS for lower power and more efficient operation

versus bipolar drivers.

• Logic Input: Will Withstand Negative Swing Up To

• ESD Protected: 4 kV

• Matched Rise and Fall Times:

- 25 ns (2500 pF load)

Both devices have TTL/CMOS-compatible inputs,

which can be driven as high as V_DD+ 0.3V or as low as

-5V without upset or damage to the device. This

eliminates the need for external level-shifting circuitry

and its associated cost and size. The output swing is

rail-to-rail, ensuring better drive voltage margin,

especially during power-up/power-down sequencing.

The propagational delay time is only 55 ns (typ.), while

the output rise and fall times are only 25 ns (typ.) into

2500 pF across the usable power supply range.

• High Peak Output Current: 6A

• Wide Input Supply Voltage Operating Range:

- 4.5V to 18V

• High Capacitive Load Drive Capability: 10,000 pF

• Short Delay Time: 55 ns (typ.)

• CMOS/TTL-Compatible Input

• Low Supply Current With Logic ‘1’ Input:

- 450 µA (typ.)

Unlike other drivers, the TC4420M/TC4429M are

virtually latch-up proof. They replace three or more

discrete components, saving PCB area and parts while

improving overall system reliability.

• Low Output Impedance: 2.5Ω

• Output Voltage Swing to Within 25 mV of Ground

or V_DD

• Wide Operating Temperature Range:

- -55°C to +125°C

Package Types:

• See TC4420/TC4429 Data Sheet (DS21419) for

additional temperature range and package

offerings.
