Microchip Technology MD1822
The MD1822 is a high-speed, four-channel MOSFET driver designed to drive high-voltage P-channel and N-channel MOSFETs for medical ultrasound applications and other applications requiring a highoutput current for a capacitive load. The high-speed input stage of the MD1822 can operate from a 1.8V to 5V logic interface with an optimum operating input signal range of 1.8V to 3.3V. The input logic levels may be ground referenced even though the driver is putting out bipolar signals.| Part No. | MD1822 |

GENERAL DESCRIPTION
An adaptive threshold circuit is used to set the level translator switch threshold to the average of the input logic 0 and logic 1 levels. The level translator uses a proprietary circuit, which provides DC coupling together with high-speed operation. The output stage of the MD1822 has separate power connections, enabling the output signal L and H levels to be chosen independently from the supply voltages used for the majority of the circuit.
