Product details

Dual low-side MOSFET driver — 1.5 A peak, 20 ns edges

The TelCom Semiconductor TSC427EPA is a dual low-side MOSFET driver for N-channel and P-channel power MOSFETs. Each of the two independent, non-inverting channels delivers 1.5 A peak source and 1.5 A peak sink current, with typical rise and fall times of 20 ns. Logic inputs are compatible with standard CMOS and TTL levels — VIL at 0.8 V, VIH at 2.4 V.

Where it fits — switching loads and gate-drive circuits

This driver is sized for applications that need to switch a pair of low-side MOSFETs at moderate frequency: DC-DC converters, motor-drive half-bridges, solenoid drivers, and class-D audio output stages. The 1.5 A peak output can charge and discharge the gate capacitance of a medium-power MOSFET in tens of nanoseconds, keeping switching losses in check.

RoHS note — verify compliance requirements

If your assembly process or end-market requires RoHS exemption or full compliance, confirm the solder-joint and material restrictions before committing the BOM.

Frequently asked questions

What is the difference between TSC427EPA and TSC428EPA?

The TSC428EPA is the inverting version of this driver family. The TSC427EPA is non-inverting — a logic high on the input turns the output high. The TSC428EPA inverts that relationship. Both share the same pinout, package, and 1.5 A peak output rating, so the choice depends on whether your PWM controller or logic output needs an inversion or not.

Can TSC427EPA drive both N-channel and P-channel MOSFETs?

Yes. The TSC427EPA is specified for driving both N-channel and P-channel MOSFETs. The low-side configuration and non-inverting input work with either channel type, as long as the gate threshold and gate charge are within the driver's 1.5 A peak output and 4.5 V to 18 V supply range.
