MP6519 2.5V - 28V, 5A, H-Bridge Current Regulator The Future of Analog IC Technology DESCRIPTION FEATURES The MP6519 is a monolithic, step-down, Wide 2.5V to 28V Operating Input Range Up to 5A Output Load Current current-source driver for applications that 2% Accuracy at Full-Scale Reference require accurate and fast current-response 65m R for Each MOSFET of H- DS(ON) control. The MP6519 achieves up to 5A of Bridge output current with excellent load and line 100% Duty Cycle Operation of H-Bridge regulation over a wide input supply range. 30kHz to 300kHz Programmable Switching The four integrated MOSFET H-bridge control Frequency provide a fast dynamic load response and an 20kHz - 100kHz PWM Input for Current ultra-high efficiency solution. For ease of use, Regulation the output polarity can be controlled by pulling Programmable Full-Scale Current Up to 94% Efficiency MODE high or low. Selectable Current Polarity Mode By setting the full-scale output current through Switching Auto-Disabled by PWM Input an external resistor, the output current can be Detection dimmed by the PWM input signal from 0 - 100% 1 A Shutdown Mode of the full-scale current range. Inherent Open-Load Protection Cycle-by-Cycle Over-Current Protection Full protection features include load open, load- (OCP) short protection, over-current protection (OCP), Output Short-Circuit Protection (SCP) over-temperature protection (OTP), and input Input Over-Voltage Protection (OVP) over-voltage protection (OVP). The MP6519 is Over-Temperature Shutdown available in a QFN-19 (3mmx3mm) package.
