MAX14914

High-Side Switch with Settable Current-Limiting,

Push-Pull Driver Option and Digital Input Conﬁguration

General Description

Beneﬁts and Features

● Reduces Power and Heat Dissipation

The MAX14914 is a high-side/push-pull driver that operates

as both an industrial digital output (DO) and an industrial

digital input (DI). The MAX14914 is specified for operation

with supplies up to 40V. The high-side switch current is

resistor settable from 135mA (min) to 1.3A (min). The

high-side driver’s on-resistance is 120mΩ (typ) at 125°C

ambient temperature. Optional push-pull operation allows

driving of cables and fast discharge of load capacitance.

The output voltage is monitored and indicated through the

DOI_LVL pin for safety applications.

• 240mΩ (max) HS R at T = 125°C

• Accurate Short-Circuit Current Limit

• Accurate Internal Current Limiter for Types 1, Type

2, and Type 3 Digital Inputs

● Enhances System Robustness

• “Safe-Demagnetization” for Safe Turn-Off of

Unlimited Inductance

• 60V Supply Tolerance

• Loss of GND Protection

• Thermal Shutdown Protection

The MAX14914 complies with Type 1, Type 2, or Type

• ±2kV IEC 61000-4-5 Surge Protection

• ±20kV IEC 61000-4-2 Air-Gap ESD Protection

• ±7kV IEC 61000-4-2 Contact ESD Protection

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

3 input characteristics when configured for DI operation.

Applications

● Industrial Digital Outputs and Inputs Modules

● Conﬁgurable Digital Input/Output

● Motor Control

● Reduces BOM Count and PCB Space

• Small 4mm x 4mm TQFN Package

• Internal Clamps for Fast Inductive Load Turn-Off

• On-Chip 5V Regulator

● Safety Systems

● Provides Flexibility

Ordering Information and Functional Diagram appears at

end of data sheet.

• Conﬁgurable as a Digital Input or a High-Side or

Push-Pull Digital Output

• Resistor Settable Current Limiting for the High-Side

Switch (135mA - 1.3A)

• 10V to 40V Operating Supply Range

● Improves System Speed and Throughput

• Propagation Delay of Less Than 2µs
