Product Details
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.
The MAX14874 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 low supply current.
The MAX14874 features shoot-through protection and internal free-wheeling diodes that absorb inductive currents. Driver outputs are short-circuit protected against shorts to the supply, and between M1 and M2. An active-low FAULT output signals thermal overload and overcurrents during fault conditions.
The MAX14874 is available in a 12-pin TDFN-EP (3mm x 3mm) package and operates over the -40°C to +85°C temperature range.
Applications
- Coffee Machines
- Motor Control
- Valve and Relay Control
