Overview
The TLE4729GNT is a smart low-side power switch from Infineon's MOTIX™ family, designed for automotive applications. It integrates a single N-channel MOSFET with comprehensive diagnostic and protection features. The device operates within a supply voltage range of 5.5 V to 18 V. Key electrical parameters include a maximum on-state resistance of 0.36 Ω at 25°C and a continuous output current capability of 2 A. It features an overcurrent limit of 10 A and supports PWM frequencies up to 1 kHz. The component utilizes a PG-DSO-8 package and is qualified to AEC-Q101 standards.
Feature Summary
- Integrates intelligent diagnostics including open-load detection and short-circuit protection
- Features thermal shutdown and reverse polarity protection for enhanced reliability
- Supports pulse width modulation (PWM) control for precise load management
Applications
- Automotive lighting systems such as headlights and interior lamps
- Control of high-current automotive loads like fans and pumps
- General purpose switching in automotive electronic control units
Procurement Notes
Verify the specific ordering suffix to confirm package type and tape-and-reel specifications. Ensure the component meets the required AEC-Q101 qualification level for your target automotive application. Cross-reference the datasheet revision date to ensure compatibility with your design requirements. Confirm that the operating temperature range aligns with your system's environmental constraints.
Selection Notes
Select this component when a single-channel smart switch with integrated diagnostics is required. It is suitable for loads requiring up to 2 A continuous current. Consider alternative MOTIX™ variants if higher channel counts or different voltage ratings are needed. Evaluate the thermal performance based on the expected duty cycle and ambient temperature conditions.
Part Context
The TLE4729GNT belongs to the MOTIX™ TLE4xxx series of smart power switches. This family is specifically engineered for robust automotive environments, offering high integration and reliability. It complements other MOTIX™ products by providing simple, cost-effective solutions for basic switching tasks with advanced fault handling capabilities.
Replacement Considerations
Check for direct cross-reference part numbers from Infineon's official cross-reference tools. Verify pinout compatibility and electrical parameter equivalence before substitution. Ensure any replacement maintains the same automotive qualification status.
