TPS60252RTET

Overview

The TPS60252RTET is a high-efficiency charge pump LED driver IC designed for seven white LEDs. It operates from a 3 V to 6 V input supply and delivers up to 230 mA output current. The device features an I2C interface for control, including dimming and configuration. It utilizes a WQFN-16 package and supports a switching frequency of 750 kHz. The output voltage reaches 6.5 V, with operation across -40°C to +85°C.

Feature Summary

• Integrates I2C interface for digital control of LED brightness and system configuration
• Provides open LED detection for fault monitoring and safety
• Includes soft-start functionality to limit inrush current during startup

Applications

• Portable electronic devices requiring backlighting
• Mobile phone display illumination systems
• Handheld instrument indicator lighting

Procurement Notes

Verify the specific suffix RTET corresponds to the tape and reel packaging format required for your assembly line. Confirm that the I2C slave address matches your system bus configuration to avoid communication conflicts. Ensure thermal management strategies align with the WQFN-16 package power dissipation limits under maximum load conditions.

Selection Notes

Select this component when a compact solution for driving multiple white LEDs from a single-cell lithium battery is needed. The I2C capability allows for precise brightness adjustment without additional analog circuitry. Consider the 230 mA current limit and 7-channel architecture against total LED string requirements to ensure adequate headroom.

Part Context

This part belongs to the TPS60250 series of charge pump drivers. It shares architectural similarities with other members like the TPS60250 but offers specific I2C integration. The series targets applications where space constraints and digital control are prioritized over simple analog dimming methods.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing firmware if replacing with other I2C-controlled LED drivers from different manufacturers.
