IXYS Features: • • • • • • • 16 Push-Pull Outputs Rated at 60V, 15mA 6V to 60V Driver Supply Range 1.65V to 5.5V Logic Supply Range I2C Interface Synchronous update across multiple packages Outputs can be paralleled 28 Lead QFN Package MX8771 16-Channel, 60V Driver Push-Pull Output, I2C Interface General Description The MX8771 is a 16 channel high voltage switch with I2C serial input control. The MX8771 connects directly to a microprocessor through a standard I2C interface. The push-pull output configuration can drive up to 60 volts at 15mA. Outputs can be paralleled for increased drive current up to a device total of 240mA sink or source. The MX8771 is designed to operate over a temperature range of -40°C to +85°C, and is available in a QFN-28 Package.

Stresses in excess of these ratings can cause permanent damage to the device. Functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this data sheet is not implied. Exposure of the device to the absolute maximum ratings for an extended period may degrade the device and affect its reliability. -55 -40 110 Typical ESD (electrostatic discharge) sensitive device. Although the MX8771 features proprietary ESD protection circuitry, permanent damage may be sustained if subjected to high energy electrostatic discharges. Proper ESD precautions are recommended to avoid performance degradation or loss of functionality.

Thermal Resistance is measured in still air with the device soldered to a 6 square inch board without a ground plane. Applications may require derating of the specified maximum currents to avoid exceeding the maximum operation junction temperature.

The first address can be set from 20h to 27h by connecting pins A2, A1, A0 according to the table below and is used to write and read from the 16-bit data register. The second address is fixed at 28h and facilitates the simultaneous update of outputs from multiple bytes and multiple MX8771's. The contents of the data register are transferred to the buffer register when the i2c master issues a read command to address 28h. The data byte that is read from 28h is a dummy byte whose value is undefined. Optionally the master can terminate the read command after issuing the address and the read bit without actually reading a byte.
