2、ung Electro-Mechanics Seoul Semiconductor TI (Texas Instruments) Walsin Technology 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

3、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 (1.8V-5.0V).The transistors can be paralleled for higher current capability.The TPL7407Ls key benefit is its improved power efficiency and l
