TC4421CAT Description

Short technical summary and product information.

The TC4421CAT from Microchip Technology is a high-current buffer/driver capable of driving large MOSFETs and IGBTs. It offers a high peak output current of 9A and a wide input supply voltage operating range from 4.5V to 18V. The device provides fast rise and fall times, with typical values of 30 ns with a 4,700 pF load, and short propagation delays of 30 ns.

 

Designed for robustness, the TC4421CAT is latch-up protected and can withstand significant output reverse current. Its inputs can be driven directly from TTL or CMOS logic, with built-in hysteresis for noise immunity. The driver is available in a space-saving TO-220-5 package, suitable for through-hole mounting.

 

Applications for the TC4421CAT include driving heavily-loaded lines, pulse generators, local power on/off switches, and motor or solenoid drivers. Its robust design and high current capability make it suitable for demanding power switching applications.
