DESCRIPTION

The MPQ6610 is a half-bridge driver with

current measurement and regulation features. It

can operate from a 4V to 55V supply voltage,

and can deliver up to 3A of output current

(depending on the package, PCB design, and

ambient temperature). The MPQ6610 can be

used to drive brushed DC motors, solenoids, or

other loads.

An internal current-sense circuit provides an

output with a voltage that is proportional to the

load current. Cycle-by-cycle current regulation

and limiting are also provided. These features

do not require the use of a low-Ohmic shunt

resistor.

Internal diagnostic and protection features

include open-load detection, over-current

protection (OCP), under-voltage lockout

(UVLO), and thermal shutdown.

The MPQ6610 is available in 8-pin TSOT23

and SOIC-8 packages. Note that due to the

small pin spacing, the TSOT23 package is only

recommended for applications up to 45V,

unless conformal coating or encapsulation is

used.
