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 (VIN) range. It can deliver up to 2A of
continuous current (IOUT), 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 (VISEN) that is proportional to the
load current (IOUT). 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 overtemperature protection (OTP).
The MP6614 requires a minimal number of
readily available, standard external
components. The MP6614 is available in a
SOIC-8EP package.
