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.
