Product details

Overview

TPS65810RTQR from Texas Instruments is a single-cell Li-ion battery and power management IC integrating charge management, nine LDOs (six adjustable, two fixed 3.3 V, one 1.5 V RTC backup), two 600 mA buck converters (SM1/SM2), white LED driver (6-LED series), RGB LED controller, PWM outputs, 8-channel ADC, and I²C host interface. It serves as the central PMIC in handheld devices requiring compact, thermally robust power sequencing.

For engineers reviewing the TPS65810RTQR datasheet, TPS65810RTQR pinout, TPS65810RTQR application, or TPS65810RTQR equivalent, this device supports critical design tasks including battery charge parameter programming (AC/USB current limits, termination thresholds), dynamic power path management (DPPM), system reset coordination, thermal foldback, and real-time pack temperature monitoring via TS pin.

Technical Context

The TPS65810RTQR implements dual-input power-path arbitration between AC and USB sources with automatic switchover (tSW < 100 μs), integrated DPPM loop that regulates SYS_IN voltage by throttling charge current when system load exceeds input capability, and thermal foldback triggered at 165°C with 30°C hysteresis. Its I²C interface (400 kHz compliant) provides full register access to all 128-bit configuration and status registers.

It integrates three independent power-stage outputs: SM1/SM2 synchronous bucks (600 mA each, 0.6–3.4 V programmable), and SM3 boost-based white LED driver (programmable constant-current up to 30 mA per string). All nine LDOs feature independent enable control, with LDO0/LDO1/LDO2 supplied from VIN_LDO02 and LDO3–LDO5 from VIN_LDO35.

Key Specifications

Pinout & Package

TPS65810RTQR uses an 8 mm × 8 mm QFN-56 package with exposed thermal pad (pin 57, connected to AGND1). The thermal pad must be soldered to a dedicated ground plane for thermal and electrical integrity; AGND0/AGND1/AGND2 and PGND1/PGND2/PGND3 are separate analog and power ground domains requiring star-point connection.

Equivalent & Alternatives

The following parts are listed as comparable options for similar power management IC applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TPS65811RTQR	Same pinout and architecture, but SM1/SM2 rated for 750 mA (vs. 600 mA); identical register map and firmware compatibility.	Preferred for systems requiring higher buck current (e.g., dual-core processors), otherwise functionally interchangeable in 600 mA-limited designs.	Select TPS65811RTQR only if >600 mA per buck is required; TPS65810RTQR remains optimal for cost-sensitive, thermally constrained layouts.
BQ24150ARHLT	Dedicated single-cell charger (no LDOs/bucks); supports 1.5 A charge, I²C, thermal regulation, but lacks integrated power rails or LED drivers.	Suitable only as a charge-only replacement; requires external LDOs, bucks, and LED drivers-increases BOM and layout complexity.	Choose BQ24150ARHLT only when existing design separates charging and power regulation; TPS65810RTQR provides full integration where space and component count matter.

Compared with TPS65811RTQR, the TPS65810RTQR offers identical feature set and pin compatibility at lower buck current rating-ideal for thermally sensitive handhelds. Versus BQ24150ARHLT, it delivers complete power system integration, eliminating 12+ discrete components while enabling dynamic DPPM and RGB control unattainable with standalone chargers.

FAQ

What is the maximum continuous output current supported by the TPS65810RTQR's main power-path output (OUT pin)?

The TPS65810RTQR supports up to 3000 mA continuous output current on the OUT pin, which serves as the primary system power rail (SYS_IN). This rating assumes proper thermal management-specifically, soldering the exposed thermal pad to a 400 mm² copper area-and operation within the recommended junction temperature range (–40°C to 125°C). The actual deliverable current depends on input source (AC/USB), battery state, and ambient conditions.

How does the Dynamic Power Path Management (DPPM) function operate in the TPS65810RTQR?

The DPPM function in the TPS65810RTQR maintains stable SYS_IN voltage by dynamically reducing battery charge current when the combined system load and charge demand exceed the available input current (AC or USB). It monitors the DPPM pin voltage and adjusts charge rate in real time-preventing system brownout during high-power events like display backlight activation or RF transmission without requiring host intervention.

Can the TPS65810RTQR drive six white LEDs in series, and what protection features apply?

Yes, the TPS65810RTQR's SM3 boost stage can drive up to six white LEDs in series with programmable constant current (up to 30 mA per string). It includes overvoltage protection clamping SM3 at 28 V, internal short-circuit detection between SM3 and PGND3, and thermal foldback that reduces LED current above 125°C-ensuring safe operation even under LED open-circuit or overvoltage fault conditions.

What are the key differences between the TPS65810RTQR and TPS65811RTQR?

The TPS65810RTQR and TPS65811RTQR share identical pinout, register map, and feature set, but differ in buck converter current ratings: TPS65810RTQR supports 600 mA per buck (SM1/SM2), while TPS65811RTQR supports 750 mA. Both use the same QFN-56 package and firmware, making them drop-in compatible where 600 mA suffices; TPS65811RTQR is selected only when higher buck current is required.

Does the TPS65810RTQR support battery temperature monitoring, and how is it implemented?

Yes, the TPS65810RTQR supports battery temperature monitoring via its TS pin, which provides a programmable current source (10–60 μA, selectable via I²C) to bias an external NTC thermistor. The resulting voltage is measured by the integrated 8-channel ADC, enabling real-time temperature tracking for charge algorithm adjustment, thermal foldback, and safety cutoff at 165°C.
