MTCH652-I/SS Information

MTCH650/2 Programmable Voltage Boost

Microchip's MTCH652 is a compact boost converter, with up to 19 level shifters, which provides an easy-to-use solution for driving High Voltage (HV) outputs. MTCH650 is a line driver device, with 21 level shifters available. The devices contain a Configuration register (CONFIG) and a data (DATA) register. The CONFIG register can be adjusted using the SPI interface, allowing for voltage changes during application time. The CONFIG register sets the output voltage, the current limit and the Soft Start settings. The DATA register configures the 19/21 bit output mask for the HV output latches. The Output Enable (OE) allows for efficient cycling of the boost voltage on the HV output latches without the delay of setting HV output latches via the serial interface. The HV output latches are set to '0' when Output Enable (OE) is '0'. The HV output latches are set to the output mask when OE is '1'. MTCH650/2 require only a 3-wire serial interface, latch enable (LE) and two capacitors. MTCH652 requires an additional PWM and a small inductor. The PWM is used to drive the boost and allows flexibility in duty cycle and frequency. The selectable internal Soft Start limits initial in-rush currents, preventing system brownouts.Learn More
