MPQ3428AGL-P Monolithic Power Systems

MPQ3428A 19A, 600kHz, 20V Wide Input Range, Synchronous Boost Converter with Input Disconnect Function, AEC-Q100 Qualified DESCRIPTION FEATURES The MPQ3428A is an Automotive AECQ Guaranteed Industrial/Automotive Temp application device with 600kHz, fixed-frequency, 3V to 20V Wide Input Range high-efficiency, wide input range, current mode Integrated 18m Low-Side Power FET boost converter, optional input disconnect and SDR Driver for Synchronous Solution an input average current limit function. The 19A Internal Switch Current Limit or input disconnect feature provides additional External Programmable Input Current protection by isolating the input from the output Limit during output short or shutdown. Input Disconnect and Output SCP External Soft Start and Compensation for With a programmable input average current Higher Flexibility limit, the MPQ3428A supports a wide range of applications, including eCall, Smart latch, Programmable UVLO and Hysteresis Telematics and infotainment. The MPQ3428A <1A Shutdown Current features a 18m, 24V power switch and a Thermal Shutdown at 150C synchronous gate driver for high efficiency. An Available in a QFN-22 (3mmx4mm) external compensation pin allows flexibility in Package setting loop dynamics and obtaining optimal Available in AEC-Q100 Grade 1 transient performance under all conditions. APPLICATIONS The MPQ3428A includes under-voltage lockout, Industrial Automotive Applications switching current limiting, and thermal eCall shutdown to prevent damage in the event of an Smart latch output overload. The MPQ3428A is available in Telematics a low-profile QFN-22 (3mmx4mm) package. Infotainment All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.
