MP6614

35V, H-Bridge DC Motor Driver in an SOIC-8EP Package

Datasheet

Description

The MP6614 is an H-bridge motor driver designed to drive reversible motors. The device can drive one DC motor, one winding of a stepper motor, or other loads. The H-bridge integrates four N-channel power MOSFETs, and an internal charge pump generates the required gate driver voltages.

The MP6614 operates across a 5V to 35V input supply (V_IN) range. It can deliver up to 2A of continuous current (I_OUT), depending on the thermal and PCB layout. The MP6614 provides a pulse-width modulation (PWM) input interface that is compatible with industry-standard devices. A brake is applied to stop the motor, and a very low standby circuit current can be achieved when the device is disabled.

An internal current-sense circuit provides an output voltage (V_ISEN) that is proportional to the load current (I_OUT). In addition, cycle-by-cycle current regulation and limiting are provided. These features do not require a low-ohmic shunt resistor.

Internal protection features include over-current protection (OCP), short-circuit protection (SCP), under-voltage lockout (UVLO), and over-temperature protection (OTP).

The MP6614 requires a minimal number of readily available, standard external components. The MP6614 is available in an SOIC-8EP package.

The EV6614-N-00A is an evaluation board designed to demonstrate the capabilities of the MP6614, an H-bridge DC motor driver. The MP6614 operates from an input voltage (V_IN) up to 35V. The H-bridge consists of four N-channel power MOSFETs, and an internal charge pump generates the required gate-drive voltages.

An internal current-sense circuit provides an output voltage (V_ISEN) that is proportional to the load current. In addition, the device provides cycle-by-cycle current regulation and limiting. These features do not require the use of a low-ohm shunt resistor.

Internal protections include over-current protection (OCP), short-circuit protection (SCP), under-voltage lockout (UVLO), and over-temperature protection (OTP). The input control signals are generated via the connector on the board.

The MP6614 is designed to drive solenoids, brushed DC motors, or other loads, and is available in an SOIC-8EP package.
