TPL7407LDR

The TPL7407LDR is a 7-channel High Voltage NMOS Transistor Array ideal for LEDs, gate and IGBT drive applications. This low side driver 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 600mA. New regulation and drive circuitry added to give maximum drive strength across all GPIO ranges (1.8 to 5.0V).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 VOL the user is dissipating less than half the power than traditional relay drivers with currents less than 250mA per channel.

• 600mA Rated drain current (per channel)
• CMOS pin-to-pin improvement of 7-channel Darlington array
• Power efficient (very low VOL)
• Very low output leakage (<lt/>10nA per channel)
• High voltage outputs
• Compatible with 1.8 to 5.0V microcontrollers and logic interface
• Internal free-wheeling diodes for inductive kick-back protection
• Input pull-down resistors allows tri-stating the input driver
• Input RC-snubber to eliminate spurious operation in noisy environment
• Green product and no Sb/Br
