GND GATE3
logic-level power DMOS array that consists of three electrically isolated independent N-channel enhancement-mode DMOS transistors. Each transistor features integrated high-current zener diodes (ZCXa and ZCXb) to prevent gate damage in the 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-p F capacitor in series with a 1.5-kΩ resistor. The TPIC5323L is offered in a standard 16-pin small-outline surface-mount (D) package and is characterized for operation over the case temperature of –40°C to 125°C.
