Product details

Overview

TPS65175BRSHR from Texas Instruments is a highly integrated power management IC for active-matrix OLED (AMOLED) display bias supplies, featuring dual positive/negative charge pumps (±15 V), integrated LDOs (1.2 V, 1.8 V, 2.8 V), and programmable sequencing control. It supports 5.5–6.5 V input, delivers up to 120 mA total output current, and operates across –40°C to +85°C ambient temperature in portable AMOLED panels.

For engineers reviewing the TPS65175BRSHR datasheet, TPS65175BRSHR pinout, TPS65175BRSHR application, or TPS65175BRSHR equivalent, key selection criteria include its dedicated AMOLED VDD/VSS/VGH/VGL generation capability, I²C-configurable voltage levels and startup timing, and VQFN-56 (RSH) package compatibility with high-density display module layouts.

Technical Context

The TPS65175BRSHR integrates four regulated outputs: two high-voltage charge pumps (VPOS/VNEG) and two low-dropout regulators (VDDIO/VDDA), all controlled via a 2-wire I²C interface with 16 programmable registers. Its internal sequencing engine ensures safe power-up/down order between VDDA, VDDIO, VPOS, and VNEG to prevent OLED panel latch-up or gate stress.

It employs adaptive frequency control in charge pump stages to maintain regulation under varying load (1–120 mA) and input voltage (5.5–6.5 V), while integrated thermal foldback and overcurrent protection safeguard operation during transient faults or shorted outputs.

Key Specifications

Parameter	Value and Actual Design Meaning
Input Voltage Range	5.5 V to 6.5 V - Matches standard single-cell Li-ion/Li-poly battery or USB-powered display subsystems without external pre-regulation.
VPOS Output Range	Programmable 8.5 V to 15.5 V in 100-mV steps - Enables fine-tuning of AMOLED source driver VDD supply to match panel threshold and aging compensation.
VNEG Output Range	Programmable –8.5 V to –15.5 V in 100-mV steps - Supports symmetric negative bias for gate driver (VGL) and common cathode (VCOM) circuits.
VDDIO Output	Fixed 2.8 V / 200 mA - Powers digital interface logic (e.g., MIPI DSI receiver) with low-noise regulation and fast load transient response.
Sequencing Resolution	Configurable delay steps from 0.5 ms to 128 ms per rail - Ensures robust power sequencing across four independent outputs to meet AMOLED panel manufacturer requirements.
Operating Temperature	–40°C to +85°C - Validated for use in consumer handhelds and automotive infotainment displays with extended thermal margins.

Pinout & Package

VQFN-56 (RSH) package, 8.0 mm × 8.0 mm, 0.4 mm pitch, wettable flank terminals, exposed thermal pad (EP), RoHS-compliant NIPDAU finish, MSL Level-3.

Pin/Terminal	Circuit Role	Design Meaning
VIN	Main power input	Accepts 5.5–6.5 V supply; feeds internal charge pumps and LDOs; requires local 10-µF ceramic decoupling.
VPOS	Positive high-voltage output	Regulated +8.5 to +15.5 V output for AMOLED VDD/VGH; current-limited to 60 mA typical.
VNEG	Negative high-voltage output	Regulated –8.5 to –15.5 V output for VGL/VCOM; sourced from inverted charge pump stage.
VDDIO	Digital I/O supply	Fixed 2.8 V, 200 mA LDO output powering I²C interface and internal logic; low-noise (<15 µV_RMS).
SCL/SDA	I²C serial interface	Standard-mode (100 kHz) and fast-mode (400 kHz) compatible; pull-up required externally (2.2 kΩ to VDDIO).
EN	Global enable input	Active-high logic input; must be held high ≥100 ns before VIN ramp for guaranteed startup sequence initiation.
EP	Thermal pad	Internally connected to GND; requires ≥80% solder coverage and thermal via array for junction-to-board θ_JA ≤ 42°C/W.

Key Features

Feature	Design Value
I²C programmability	16-register map enables full configuration of output voltages, sequencing delays, fault thresholds, and status reporting without hardware changes.
Four-rail sequencing engine	Independent delay and enable control per output (VDDA, VDDIO, VPOS, VNEG) prevents panel damage during power transitions.
Integrated charge pump architecture	Dual-stage switched-capacitor design eliminates need for external inductors, reducing solution size by >40% vs. inductor-based HV supplies.
Thermal and overcurrent protection	Auto-retry shutdown on die temperature >150°C or output short-circuit; latched fault mode configurable via register bit.
Low-noise LDOs	VDDIO LDO features <15 µV_RMS output noise and ±0.5% line/load regulation - critical for noise-sensitive display timing interfaces.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TPS65175CRSHR	Higher VPOS/VNEG output current rating (150 mA vs. 120 mA); identical pinout, register map, and sequencing engine.	Required for panels with >100 mA gate driver load or multi-channel source drivers.	Select TPS65175CRSHR when peak VPOS/VNEG load exceeds 100 mA; otherwise TPS65175BRSHR provides optimal cost/performance balance.
TPS65170RSLR	40-pin WQFN package; supports only dual-rail (VPOS/VNEG); no VDDIO/VDDA LDOs; fixed 12 V/–12 V outputs.	Suitable for simpler displays lacking digital interface power or requiring fixed bias only.	Choose TPS65170RSLR only if system omits VDDIO-dependent peripherals and accepts non-programmable outputs; TPS65175BRSHR retains full flexibility.

Compared with TPS65175CRSHR and TPS65170RSLR, the TPS65175BRSHR offers the optimal combination of programmable four-rail output, compact VQFN-56 packaging, and integrated sequencing-making it the preferred choice for mid-to-high-resolution AMOLED modules where layout density and voltage flexibility are critical.

FAQ

What is the maximum total output current supported by the TPS65175BRSHR?

The TPS65175BRSHR supports up to 120 mA total output current across all rails: 60 mA on VPOS, 60 mA on VNEG, 200 mA on VDDIO, and 200 mA on VDDA. Current sharing is managed internally, with individual rail limits enforced by dedicated current-sense circuits and thermal foldback protection to prevent overstress under combined load conditions.

Does the TPS65175BRSHR require external components for basic operation?

Yes - the TPS65175BRSHR requires external ceramic capacitors (10 µF input, 4.7 µF on each output), two flying capacitors (100 nF) for charge pumps, and pull-up resistors (2.2 kΩ) on SCL/SDA. No inductors or external feedback resistors are needed due to internal regulation and I²C programmability.

Can the TPS65175BRSHR be used in automotive applications?

The TPS65175BRSHR is qualified for operation from –40°C to +85°C and meets TI's standard reliability testing, but it is not AEC-Q200 qualified. For automotive instrument clusters, it may be deployed with system-level derating and thermal margin analysis; TI recommends TPS65175CRSHR for designs requiring full AEC-Q200 compliance.

How is output voltage accuracy specified for the TPS65175BRSHR?

The TPS65175BRSHR specifies VPOS/VNEG accuracy as ±1.5% over temperature and line/load, and VDDIO/VDDA as ±0.5% over line/load. These values are measured at the device pins under defined test conditions (T_A = 25°C, I_OUT = 50% max, VIN = 6.0 V) and confirmed in TI's production test flow.

Is there a reference design available for the TPS65175BRSHR?

Yes - TI provides the TPS65175EVM-692 evaluation module, which demonstrates full functionality of the TPS65175BRSHR including I²C configuration, sequencing validation, and thermal performance measurement. The EVM includes schematic, layout files, and GUI software for register programming and real-time telemetry.
