Key Features
- 8-channel open-drain relay/load driver with up to 500 mA per channel sink current for driving inductive loads directly from MCU GPIO
- Integrated transient, thermal, over-voltage, and short-circuit protection eliminates the need for external protection diodes on all 8 channels
- Space-saving 20-pin 5x5x0.75 mm QFN package reduces PCB footprint compared to discrete MOSFET or Darlington relay driver solutions
- SPI-compatible serial interface allows all 8 channels to be controlled with only 3-4 GPIO lines from any microcontroller
Applications
The MAX4896ATP+ is used in relay-driver boards, industrial solenoid controllers, and building automation systems where up to 8 inductive loads must be switched independently under microcontroller command. Its integrated protection features make it ideal for PLC output modules, HVAC valve drivers, and smart home relay panels that require short-circuit and transient immunity without external TVS diodes. The compact 20-pin QFN package enables high-channel-density relay arrays on space-constrained PCBs in embedded industrial and automotive body-electronics applications.

Frequently Asked Questions
How many channels does the MAX4896ATP+ support, and what is the output configuration?
The MAX4896ATP+ provides 8 independent channels with open-drain outputs, each capable of sinking up to 500 mA. The open-drain topology allows load voltages higher than the supply rail to be switched, making it suitable for driving 12 V or 24 V relays and solenoids from a 3.3 V or 5 V microcontroller.
What built-in protections does the MAX4896ATP+ offer for industrial relay driving applications?
The MAX4896ATP+ integrates transient voltage suppression, thermal shutdown, over-voltage protection, and short-circuit protection on all 8 channels. These built-in protections eliminate the need for external TVS diodes on inductive loads and protect the IC during relay coil back-EMF spikes, which can reach 40 V or more in 24 V relay circuits.
What package does the MAX4896ATP+ use and how does it save board space compared to discrete drivers?
The MAX4896ATP+ is packaged in a 20-pin QFN measuring 5x5x0.75 mm. Compared to 8 discrete MOSFET relay drivers — which would require 8 transistors, 8 flyback diodes, and 8 gate resistors — this single IC replaces approximately 24 discrete components, reducing PCB area by roughly 60% in a typical 8-relay output module.
Can MAX4896ATP+ interface directly with a 3.3 V microcontroller in an industrial control design?
Yes, the MAX4896ATP+ is designed to accept 3.3 V logic-level inputs from standard microcontroller GPIO pins while switching loads at higher voltages such as 12 V or 24 V on the open-drain outputs. This makes it directly compatible with ARM Cortex-M, AVR, and PIC microcontrollers operating at 3.3 V in industrial PLC and relay control applications.
