Operation in Noisy Environment
• Inductive Load Driver Applications
• ESD Protection Exceeds JESD 22
– 2-kV HBM, 500-V CDM
2 Applications
• Inductive Loads
– Relays
– Unipolar Stepper & Brushed DC Motors
– Solenoids & Valves
• LEDs

• Gate & IGBT Drive
3 Description
The TPL7407LA 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'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.
