The TPIC5421L is a monolithic gate-protected  
logic-level power DMOS array that consists of four  
electrically isolated N-channel enhancement-  
mode DMOS transistors, two of which are  
configured with common source. Each transistor  
features integrated high-current zener diodes

event that an overstress condition occurs. These  
zener diodes also provide up to 4000 V of ESD  
protection when tested using the human-body  
model of a 100-pF capacitor in series with a 1.5-kΩ  
resistor.

The TPIC5421L is offered in a 20-pin wide-body  
surface-mount (DW) package and a 16-pin  
thermally-enhanced dual-in-line (NE) package  
and is characterized for operation over the case  
temperature of 40°C to 125°C.
