Eight-channel low-side driver with SPI and fault detection
The MAX4896ETP+ is an 8-channel low-side power driver from Analog Devices, designed to switch relays, solenoids, and other inductive or resistive loads under SPI control.
Load voltage and protection suite
Integrated fault protection includes fixed current limiting, open-load detection, and over-temperature shutdown — the open-load detect flag is useful for verifying that a solenoid or relay coil is actually connected before the driver energises it. A status flag output reports fault conditions to the host microcontroller, and the non-inverting input logic means a logic-high on the SPI command turns the corresponding output on.
Package and board integration
The part is supplied in a tube — suitable for low-volume prototyping and manual assembly; for reflow, the tube orientation matches standard pick-and-place feeders.
