MAX14914BATE+

Overview

The MAX14914BATE+ is a high-side power switch with integrated current limiting, manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates with an input voltage up to 100V and features a supply-independent three-state PWM input logic interface. The device provides a maximum output current of 1.3A and exhibits a typical on-resistance of 120 milliohms. It is housed in a 16-TQFN (4x4) surface-mount package. The component supports adjustable current limiting and includes over-temperature fault protection with status flag indication. It functions within a temperature range of -40°C to 125°C.

Feature Summary

• Integrates high-side switching capability with adjustable current limiting for load protection
• Features supply-independent three-state PWM input logic for flexible control interfaces
• Includes built-in over-temperature fault protection and status flag reporting

Applications

• High-side load switching in automotive systems
• Power distribution management in industrial equipment
• Motor control applications requiring current limiting

Procurement Notes

Verify the specific suffix 'ATE+' against official Analog Devices documentation to confirm the exact temperature grade and packaging configuration. Ensure compatibility with the 16-TQFN footprint during PCB layout review. Confirm that the 100V input rating aligns with system requirements. Check for any recent lifecycle changes or obsolescence notices directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a robust high-side switch with integrated protection is required. The 1.3A output current and 120 milliohm on-resistance suit moderate power loads. The three-state PWM input allows for precise duty cycle control without level shifting. Consider the 16-TQFN package size for space-constrained designs. Evaluate the thermal performance given the 125°C operating limit and internal heat dissipation characteristics.

Part Context

The MAX14914 belongs to a family of high-side switches designed for reliable power management. This specific variant, MAX14914BATE+, emphasizes current limiting and thermal protection. It complements other power management ICs by providing direct load control with diagnostic feedback. The device integrates seamlessly into systems requiring isolated or protected power delivery channels.
