MAX4824PMB1

MAX4824PMB1 Peripheral Module

Description

The MAX4824PMB1 peripheral module provides the necessary hardware to interface the MAX4824 8-channel relay driver to any system that utilizes PmodTM-compatible expansion ports configurable for GPIO communication. Each independent channel in the IC features a 2.7I(typ) on-resistance and is guaranteed to sink 70mA (min) of load current. A zener kickback-protection circuit significantly reduces recovery time in applications where switching speed is critical. When driving relays, a unique power-save mode allows relay current to be reduced to a level just above the relay hold-current threshold. This mode keeps the relay activated while significantly reducing the power consumption.
Refer to the MAX4824 IC data sheet for detailed information regarding operation of the IC.
