MP6519A

MP6519A

2.5V to 28V, 5A, Full H-Bridge Current Regulator

Datasheet

Description

The MP6519A is a monolithic, step-down, current-source driver for applications that require accurate and fast current response control. The MP6519A achieves up to 5A of output current (I_OUT), with excellent load and line regulation across a wide input voltage (V_IN) supply range.

The MP6519A provides H-bridge control with four integrated MOSFETs to achieve fast dynamic load response and an ultra-high efficiency solution. For ease of use, the output polarity can be controlled by pulling the MODE pin high or low.

By setting the full-scale I_OUT through an external resistor, I_OUT can be dimmed by the pulse-width modulation (PWM) input signal from 0% to 100% of the full-scale current range.

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 MP6519A is available in a QFN-19 (3mmx3mm) package.
