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 Reduces Power and Heat Dissipation family of high-side/push-pull drivers that operate as both 240m (max) HS R at T = 125C ON A an industrial digital output (DO) and an industrial digital in- 0.9mA (typ) High-Side DO-Mode Supply Current put (DI). The MAX14914 family features full IEC 61131-2 Accurate Internal Current Limiter for Type 1, Type compliance in both their DO and DI modes of operation. 2, and Type 3 Digital Inputs The high-side switch current is resistor settable from Enhances System Robustness 135mA (min) to 1.3A (min). The high-side drivers on-re- TM SafeDemag for Safe Turn-Off of Unlimited sistance is 120m (typ) at 125C ambient temperature. Inductance Optional push-pull operation allows driving of cables and 60V Supply Tolerance fast discharge of load capacitance. The output voltage Accurate Short-Circuit DO Mode Current Limiting is monitored and indicated through the DOI LVL pin for 2kV IEC 61000-4-5 Surge Protection safety applications. 20kV IEC 61000-4-2 Air-Gap ESD Protection The MAX14914 family complies with Type 1, Type 2, or 7kV IEC 61000-4-2 Contact ESD Protection Type 3 input characteristics when configured for DI opera- -40C to +125C Ambient Operating Temperature tion. Reduces BOM Count and PCB Space The MAX14914A is a low-DOI-leakage version of Small 4mm x 4mm TQFN Package MAX14914, designed to work together with the Internal Clamp for Fast Inductive Load Turn-Off MAX22000 Industrial Configurable Analog IO device. The On-Chip 5V Regulator MAX14914B features a high-side switch overcurrent indi- Provides Flexibility cation. Configurable as a Digital Input, or a High-Side or Push-Pull Digital Output Applications Low-Leakage Mode (MAX14914A) Allows High Industrial Digital Outputs and Inputs Modules Accuracy AIO/DIO applications Configurable Digital Input/Output Resistor Settable Current Limiting for the High-Side Motor Control Switch (135mA to 1.3A) Safety Systems Pin-Selectable Type 1/3 or Type 2 DI Operation Improves System Speed and Throughput Propagation Delay of Less Than 2s Ordering Information and Typical Application Diagram appears at end of data sheet.
