MPQ6519

3V to 28V, 5A,

H-Bridge Current Regulator,

AEC-Q100 Qualified

DESCRIPTION

FEATURES



Wide 3V to 28V Operating Input Range

Up to 5A Output Load Current

± 2% Accuracy at Full-Scale Reference

65mΩ R_DS(ON)for Each MOSFET of H-

Bridge

The MPQ6519 is a monolithic, step-down

current-source driver for applications that

require accurate and fast current-response

control. The MPQ6519 achieves up to 5A of

output current with excellent load and line

regulation over a wide input supply range.



100% Duty Cycle Operation of H-Bridge

30kHz to 300kHz Programmable Switching

Frequency

The four integrated MOSFET H-bridge controls

provide a fast dynamic load response and an

ultra-high efficiency solution. For ease of use,

the output polarity can be controlled by pulling

MODE high or low.



20kHz to 100kHz PWM Input for Current

Regulation



Programmable Full-Scale Current

Up to 94% Efficiency

Selectable Current Polarity Mode

Switching Auto-Disabled by PWM Input

Detection

By setting the full-scale output current through

an external resistor, the output current can be

dimmed by the PWM input signal from 0% to

100% of the full-scale current range.



Shutdown Mode

Inherent Open-Load Protection

Cycle-by-Cycle Over-Current Protection

(OCP)

Full protection features include open-load

protection, load-short protection, over-current

protection (OCP), over-temperature protection

(OTP), and input over-voltage protection (OVP).

The MPQ6519 is available in a QFN-19

(4mmx4mm) package.



Output Short-Circuit Protection (SCP)

Input Over-Voltage Protection (OVP)

Over-Temperature Shutdown

Available in a QFN-19 (4mmx4mm)

Package



Available in AEC-Q100 Grade 1

APPLICATIONS



Current Regulators

DC Motors

Solenoid/Actuators
