Features:

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.

• 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

The MX8771 is designed to operate over a

temperature range of -40°C to +85°C, and is

available in a QFN-28 Package.

Applications:

• White Goods

• ATE

• Industrial Equipment

Absolute Maximum Ratings (Voltages with respect to GND=0V)

Absolute Maximum Ratings are

stress ratings. 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.

ESD Warning

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.

Notes: To avoid unwanted output during VPWR application and system initialization, either reset the

device (RSTN logic low) or maintain OE logic low until the registers are initialized by I2C control.

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 MX8771 responds to two different slave addresses. 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

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.
