Product details

What this 8-channel driver does on the board

The MAX4825ETP+ is an 8-channel low-side N-channel power driver from Analog Devices, designed to switch relay coils, solenoids, or other inductive loads directly from a microcontroller's parallel port. The input-to-output ratio is 1:8, meaning one parallel data word controls all eight channels simultaneously — no serial shift register or latch needed, which simplifies the firmware and reduces the GPIO count on the host controller.

No separate Vcc supply is needed for the driver logic — the part is powered entirely through the load supply, which simplifies the power tree on a mixed-voltage board.

Frequently asked questions

What is the output current per channel on MAX4825ETP+?

Each of the eight outputs can sink up to 70 mA continuously, with a typical on-resistance of 2.7 Ohm. The actual current is limited by the load supply voltage and the PCB thermal management.

What package does MAX4825ETP+ come in?

It is supplied in a 20-lead TQFN with an exposed pad (4x4 mm body), shipped in a tube.
