MAX14917

Industrial Octal High-Side Switch

General Description

Benefits and Features

The MAX14917 has eight high-side switches specified to

deliver up to 700mA (min) continuous current per channel.

The high-side switches have on-resistance of 120mΩ (typ)

at 25°C ambient temperature.

● Robust Solutions

• 65V Absolute Maximum Supply Range

• CRC Error Checking on the SPI Interface

• Watchdog Timers for Monitoring SPI and SYNCH

• Per Channel Overload Diagnostic and Protection

The device has an SPI interface that can be daisy

chained, allowing communication with multiple MAX14917

devices utilizing a common SPI chip select (CS). There

are also per-channel overload diagnostics provided

through the SPI interface. Two watchdog timers provide

an additional safety check of the master-to-device connec-

tivity.

• Loss of V

or GND Protection

• Thermal Shutdown Protection

• Integrated ±1kV / 42Ω IEC 61000-4-5 Surge

Protection

• ±7kV / IEC 61000-4-2 Contact Discharge Method

• ±30kV / IEC 61000-4-2 Air Discharge Method

• -40°C to +125°C Operating Ambient Temperature

The MAX14917 features a 4 x 4 LED cross-bar matrix,

which provides a visual indication of channel status and

overload conditions for each channel, and an integrated

line-to-ground and line-to-line surge protection provides

robustness to the electrical stress as per IEC 61000-4-5

● Reduces Power and Heat Dissipation

• 120mΩ (typ) On-Resistance at T = 25°C

• 2.5mA (typ) Supply Current

• Accurate Output Current Limiting

and requires only one TVS on V . The MAX14917 is

● Flexible

available in a compact 48-pin 6mm x 6mm FC2QFN pack-

age.

• SYNCH Input for Simultaneous Update of Switches

• LED Driver Matrix for 16 LEDs, Powered from 3.0V

to 36V

• Internal Clamps for Fast Inductive Load

Demagnetization

• Daisy Chainable SPI

Applications

● Industrial Digital Outputs

● PLC Systems

• Flexible Logic Voltage Interface from 2.5V to 5.5V

• Pin Compatible with the MAX14915 and MAX14916

in Daisy-Chain Configuration

● Factory Automation

● Building Automation

● Industrial IoT

● Compact 6mm x 6mm FC2QFN Package
