3 Description

The TPL7407L 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 – 5.0 V).The

transistors can be paralleled for higher current

capability.

The TPL7407L's 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.
