TI TPL7407LPWR

TPL7407L is a high-voltage, high-current NMOS transistor array. The device contains 7 NMOS transistors with high-voltage outputs, featuring common-cathode clamp diodes for switching inductive loads. The maximum drain current rating for a single NMOS channel is 600mA. An enhanced voltage regulation and drive circuit provides maximum drive strength across the full GPIO range (1.8V - 5.0V). The transistors can be connected in parallel for higher current capability. The key advantage of the TPL7407L is its improved efficiency and lower leakage compared to bipolar Darlington devices. With a lower V_OL, power dissipation is reduced by half compared to conventional relay drivers at currents below 250mA per channel.
