Product details

Multi-Function Controller for 1-Cell Li-Ion/Polymer

The TPS65014RGZT is a Multi-Function Controller from Texas Instruments, designed to manage a single-cell Lithium Ion or Polymer battery. It integrates I²C and USB interfaces for communication, allowing the host system to configure charging parameters and monitor battery status.

Over-Temperature Protection and Industrial Temp Range

Built-in Over Temperature fault protection shuts down the controller if the die exceeds safe limits — a critical safeguard for Li-ion cells that can vent or catch fire if overcharged or overheated.

Active Production – Sourced per RFQ

Frequently asked questions

How can I order TPS65014RGZT or check stock?

Submit an RFQ with your target quantity. The part is Active and ROHS3 compliant, so lead times are standard for a current TI PMIC.

What is the function of TPS65014RGZT?

It is a Multi-Function Controller for a single-cell Lithium Ion or Polymer battery. It handles charge management, system power control, and communicates via I²C and USB. It is not a standalone charger — it coordinates with the host MCU.

Does TPS65014RGZT have over-temperature protection?

Yes. The datasheet lists Over Temperature as a fault protection feature. If the die exceeds the thermal threshold, the controller shuts down to protect the battery and the circuit.

What is the closest functional second-source for TPS65014RGZT?

The BQ79612PAPRQ1 is a peer from TI's automotive-grade battery monitor family, but it is not a direct second-source. The BQ79612 uses SPI/UART (not I²C/USB), targets functional-safety applications, and operates up to 125°C. For a drop-in replacement, stick with the TPS65014 series or confirm pin-compatibility with TI's cross-reference tool.
