MPQ6519 3V to 28V, 5A, H-Bridge Current Regulator, AEC-Q100 Qualified DESCRIPTION FEATURES The MPQ6519 is a monolithic, step-down Wide 3V 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 MPQ6519 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 controls Frequency provide a fast dynamic load response and an 20kHz to 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% to Shutdown Mode 100% of the full-scale current range. Inherent Open-Load Protection Cycle-by-Cycle Over-Current Protection Full protection features include open-load (OCP) protection, load-short protection, over-current Output Short-Circuit Protection (SCP) protection (OCP), over-temperature protection Input Over-Voltage Protection (OVP) (OTP), and input over-voltage protection (OVP). Over-Temperature Shutdown The MPQ6519 is available in a QFN-19 Available in a QFN-19 (4mmx4mm) (4mmx4mm) package. Package Available in AEC-Q100 Grade 1 APPLICATIONS Current Regulators DC Motors Solenoid/Actuators All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.
