The TPL7407LA is a high-voltage, high-current NMOS transistor array. This device consistsof seven NMOS transistors that feature high-voltage outputs with common-cathode clamp diodes forswitching inductive loads. The maximum drain-current rating of a single NMOS channel is 600 mA. Newregulation and drive circuitry added to give maximum drive strength across all GPIO ranges (1.8 V–5V).The transistors can be paralleled for higher current capability.
The TPL7407LA key benefit is its improved power efficiency and lower leakage than aBipolar Darlington Implementation. With the lower VOL the user isdissipating less than half the power than traditional relay drivers with currents less than 250 mAper channel.
