The MPQ5613D-AEC1 is an integrated power supply for an automotive TFT LCD bias. The device integrates a boost converter, a synchronous buck-boost inverter, an adjustable positive charge pump output, and an adjustable negative charge pump output for the gate voltages. It also includes a VCOM buffer and gate voltage shaping function to minimize the external components. The MPQ5613D-AEC1 is designed to power TFT LCD panels from a regulated 3.3V or 5V supply, or the 12V battery directly.

The VDDP can output a maximum 21.8V voltage, the VDDN can output a minimum -16.6V negative voltage, the VGH can output a maximum 35V voltage, and the VGL can output a minimum -15.9V negative voltage.

The I²C interface and configurable power-on sequences for VDDP, VDDN, VGH, and VGL make the IC suitable for different applications.

An internal soft-start function prevents input overload at start-up. The cycle-by-cycle current-limit protection for SWP and SWN reduces component stress.

Robust protections are designed to guarantee safe operation of the device. Protection modes include input under-voltage lockout (UVLO), cycle-by-cycle current-limit protection for SWP and SWN, over-temperature protection (OTP), under-voltage protection (UVP) for VDDP, VDDN, VGH, and VGL, output over-current protection (OCP) for VCOM, and output current-limit protection for VDDP.

The MPQ5613D-AEC1 is available in a tiny QFN-28 (4mmx5mm) package. It is available in AEC-Q100 Grade 1.
