MAX14914, MAX14914A,

High-Side Switch with Settable

MAX14914B

Current-Limiting, Push-Pull Driver Option and

Digital Input Configuration

General Description

Benefits and Features

The MAX14914, MAX14914A and MAX14914B are the

family of high-side/push-pull drivers that operate as both

an industrial digital output (DO) and an industrial digital in-

put (DI). The MAX14914 family features full IEC 61131-2

compliance in both their DO and DI modes of operation.

The high-side switch current is resistor settable from

135mA (min) to 1.3A (min). The high-side driver’s on-re-

sistance 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.

● Reduces Power and Heat Dissipation

• 240mΩ (max) HS R at T = 125°C

• 0.9mA (typ) High-Side DO-Mode Supply Current

• Accurate Internal Current Limiter for Type 1, Type

2, and Type 3 Digital Inputs

● Enhances System Robustness

• SafeDemag

Inductance

for Safe Turn-Off of Unlimited

• 60V Supply Tolerance

• Accurate Short-Circuit DO Mode Current Limiting

• ±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

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

Type 3 input characteristics when configured for DI opera-

tion.

● Reduces BOM Count and PCB Space

• Small 4mm x 4mm TQFN Package

• Internal Clamp for Fast Inductive Load Turn-Off

• On-Chip 5V Regulator

The MAX14914A is a low-DOI-leakage version of

MAX14914, designed to work together with the

MAX22000 Industrial Configurable Analog IO device. The

MAX14914B features a high-side switch overcurrent indi-

cation.

● Provides Flexibility

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

Push-Pull Digital Output

• Low-Leakage Mode (MAX14914A) Allows High

Accuracy AIO/DIO applications

• Resistor Settable Current Limiting for the High-Side

Switch (135mA to 1.3A)

Applications

● Industrial Digital Outputs and Inputs Modules

● Configurable Digital Input/Output

● Motor Control

● Safety Systems

• Pin-Selectable Type 1/3 or Type 2 DI Operation

● Improves System Speed and Throughput

• Propagation Delay of Less Than 2μs
