3 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 V_OL the user is
dissipating less than half the power than traditional
relay drivers with currents less than 250 mA per
channel.
