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.
