MAX14915

Compact Industrial Octal

High-Side Switch with Diagnostics

General Description

Beneﬁts and Features

The MAX14915 has eight high-side switches specified to

deliver up to 700mA continuous current. The high-side

switches have on-resistance of 250mΩ (max) at 125°C

ambient temperature.

● Robustness and Smart Diagnostics

• 65V Absolute Maximum Supply Range

• Internal Clamps for Fast Inductive Load

Demagnetization

• CRC Error Checking on the SPI Interface

• Watchdog Timer for Diagnostics Checking

• Open-Wire Detection, Both with Switches On and Oﬀ

• Undervoltage Detection with UVLO

The SPI interface has a built-in chip addressing decoder,

allowing communication with multiple MAX14915s utilizing

a common SPI chip select (CS).

The SPI interface provides flexibility for global and

per-channel configuration and diagnostic, including over

and undervoltage detection, open wire/load detection,

overload and current limiting reporting, thermal conditions

reporting, and more.

• Loss of V

or GND Protection

• Thermal Shutdown Protection

• Integrated ±1kV/42Ω IEC61000-4-5 Surge

Protection

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

Open load detection detects both open-wire/open-load

conditions with switches in the on and off states. LED

drivers provide indication of per-channel fault, status, and

supply undervoltage conditions. Internal active clamps

allow for fast turn-off of inductive loads.

● Reduces Power and Heat Dissipation

• 250mΩ (Max) On-Resistance at T = 125°C

• 2mA (typ) Supply Current

• Accurate Output Current Limiting

● Flexibility

Integrated line-to-ground and line-to-line surge protection

• Addressable SPI Interface Reduces Isolation Cost

• SYNCH Input for Simultaneous Update of Switches

• LED Driver Matrix for 16 LEDs, Powered by 24V,

5V, or 3.3V

only requires a TVS on V

The MAX14915 is available in a compact 48-pin 6mm x

6mm QFN package.

• Flexible Logic Voltage Interface from 2.5V to 5.5V

Applications

● Industrial Digital Outputs

● Compact 6mm x 6mm QFN Package

● PLC Systems
