TPB4056A20-ES1R

Overview

The TPB4056A20-ES1R is a linear lithium-ion battery charger IC manufactured by 3PEAK. It supports an input voltage range up to 26.5V, accommodating automotive or industrial supply variations without damage from pulses. The device delivers a maximum charging current of 1A and features programmable charge termination via an external resistor. It implements standard CC/CV charging profiles with automatic recharge functionality. The component includes thermal regulation to limit junction temperature during high-power dissipation.

Feature Summary

• Supports input voltages up to 26.5V for robust operation in noisy environments
• Integrates thermal regulation to prevent overheating during charging cycles
• Enables programmable charge current setting through a single external resistor
• Provides automatic recharge capability when battery voltage drops below threshold

Applications

• Automotive driving recorders requiring backup power management
• Portable consumer electronics powered by USB or DC sources
• Industrial control modules with battery backup systems
• IoT devices utilizing single-cell lithium-ion batteries

Procurement Notes

Verify the exact suffix 'ES1R' against official 3PEAK documentation to confirm package type and tape/reel specifications. Ensure compatibility with the intended PCB footprint and soldering profile. Cross-reference the part number with authorized distributors to avoid counterfeit components. Confirm that the 26.5V input rating aligns with your system's maximum supply voltage under all operating conditions.

Selection Notes

Select this component when a linear charger is preferred over switching types for lower noise sensitivity. It is suitable for applications where the voltage differential between input and battery is moderate. Consider the thermal performance requirements if operating at full 1A current. Verify that the external resistor network can achieve the desired current precision within the system's tolerance limits.

Part Context

This part belongs to the TPB4056 series of linear chargers from 3PEAK. It is designed as a drop-in replacement for industry-standard 56-series chargers. The ES1R suffix typically denotes specific packaging and handling configurations. It complements other 3PEAK power management solutions like LDOs and DCDC converters in complete system designs.

Replacement Considerations

Direct pin-compatible substitutes may include generic TP4056 variants, but electrical parameters such as input voltage tolerance and quiescent current must be verified. Alternative 3PEAK models should be checked for identical thermal characteristics and current accuracy.
