Maxim Integrated – MAX14874: 4.5V to 36V Dual Relay/ Valve/Motor Driver

The MAX14874 dual push-pull driver provides a small and simple solution for driving and controlling relays and valves with voltages between 4.5V and 36V. It is also designed to drive brushed DC motors. Separate COM pins allow monitoring of individual driver load currents. Peak currents up to 2.5A ensure for PWM controlled large motor torque. Low driver on-resistance reduces power dissipation. The MAX14874 features a charge-pump-less design for reduced external components and supply current.
