3 Description

The TPL7407LA-Q1 is a high-voltage, high-current

NMOS transistor array. This device consists of seven

NMOS transistors that feature high-voltage outputs

with common-cathode clamp diodes for switching

inductive loads. The maximum drain-current rating of

a single NMOS channel is 600 mA. New regulation

and drive circuitry added to give maximum drive

strength across all GPIO ranges (1.8 V–5 V).The

transistors can be paralleled for higher current

capability.

The TPL7407LA-Q1 key benefit is its improved power

efficiency and lower leakage than a Bipolar Darlington

Implementation. With the lower VOL the user is

dissipating less than half the power than traditional

relay drivers with currents less than 250 mA per

channel.
