Key Featrues
Resistor-Settable Current Limiting: The high-side switch current can be precisely set from 135mA to 1.3A using an external resistor, providing tailored current control for different loads. This ensures optimized performance and protection against overcurrent conditions.
SafeDemag™ for Inductive Loads: The SafeDemag™ feature ensures safe turn-off of inductive loads, preventing voltage spikes and enhancing system robustness. This is particularly beneficial in applications involving relays, solenoids, or motors.
Low On-Resistance (120mΩ Typ): With a low on-resistance of 120mΩ at 125°C, the MAX14914 minimizes power dissipation and heat generation, improving efficiency and reliability in high-temperature environments.
Integrated ESD and Surge Protection: The device offers robust protection against electrostatic discharge (ESD) and surge events, meeting IEC 61000-4-2 and IEC 61000-4-5 standards. This ensures reliable operation in harsh industrial environments, reducing the risk of damage.
Applications
Motor Control Systems: The MAX14914 is well-suited for motor control applications, offering high-speed operation and accurate current limiting. Its push-pull driver option and SafeDemag™ feature ensure safe and efficient control of inductive loads, making it ideal for motor drives in robotics and industrial machinery.
Safety Systems and Emergency Shutdown: With its high-side switch capability and built-in fault protection (current limiting and over-temperature), the MAX14914 is perfect for safety-critical systems. Its ability to handle ±2kV surge protection and ±20kV ESD protection ensures reliable operation in harsh environments, such as emergency shutdown systems in industrial plants.
Precision Digital Input Modules: The MAX14914 is ideal for precision digital input modules, offering low-leakage mode (MAX14914A) for high-accuracy applications. Its configurable Type 1/3 or Type 2 digital input operation and internal 5V regulator reduce BOM count and PCB space, making it suitable for compact and accurate digital input systems in process control and monitoring.
