Texas Instruments TPS65180BRGZR

Overview

TPS65180BRGZR from Texas Instruments is a single-chip PMIC optimized for E Ink® Vizplex™ electronic paper displays, integrating two adjustable LDOs (±15 V, 120 mA), dual charge pumps (VDDH at 22 V/10 mA and VEE at –20 V/12 mA), a boost converter (DCDC1), an inverting buck-boost converter (DCDC2), I²C-controlled VCOM driver (–0.3 V to –2.5 V, ±1.5% accuracy), thermistor monitoring, and power-good signaling - all in a 48-pin VQFN package.

For engineers reviewing the TPS65180BRGZR datasheet, TPS65180BRGZR pinout, TPS65180BRGZR application, or TPS65180BRGZR equivalent, key selection criteria include ±15-V LDO tracking tolerance (±50 mV), I²C slave address 0x48h, thermal shutdown at 150°C, 3–6 V input range, and support for EPSON S1D13522/S1D13521 timing controllers.

Technical Context

The TPS65180BRGZR implements a tightly coordinated multi-rail architecture: DCDC1 generates +17 V from 3–6 V input, boosted to +22 V by CP1 for gate drivers; DCDC2 generates –17 V, inverted to –20 V by CP2. LDO1 (VPOS) and LDO2 (VNEG) track with ±50 mV matching across load and temperature, while the VCOM driver provides 8-bit programmable bias (11-mV step) with integrated 15-mA switch and ±1°C thermistor measurement accuracy (0°C–50°C).

Power sequencing is fully configurable via I²C registers (PWR_SEQx), supporting flexible startup/shutdown order. The device operates in ACTIVE, STANDBY, and SLEEP modes, with WAKEUP pin control and open-drain nINT/PWR_GOOD outputs for fault reporting and system coordination - critical for low-power e-reader battery management.

Key Specifications

Pinout & Package

TPS65180BRGZR uses a thermally enhanced 48-pin VQFN (RGZ) package with 7.00 mm × 7.00 mm body size and exposed PowerPAD (PBKG, Pin 23) tied to VN for optimal thermal performance.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PMIC applications.

Compared with TPS65181BRGZR, the TPS65180BRGZR requires explicit I²C-triggered temperature reads and manual INT register clearing - increasing firmware overhead but offering tighter control over sensor timing. Compared with TPS65180RGER, the TPS65180BRGZR provides full VCOM programmability, thermistor interface, and independent rail enables essential for 9.7-inch Vizplex systems.

FAQ

What is the input voltage range supported by the TPS65180BRGZR?

The TPS65180BRGZR supports an input voltage range of 3 V to 6 V at VIN, VIN_P, and VIN3P3 pins. This accommodates single-cell Li-ion batteries (3.0–4.2 V) and regulated 3.3 V or 5 V system supplies without external pre-regulation. Operation outside this range risks damage, as absolute maximum ratings cap input at 7 V.

How does the TPS65180BRGZR achieve VPOS and VNEG voltage tracking?

The TPS65180BRGZR achieves VPOS and VNEG tracking through matched internal feedback networks and shared reference circuitry. When configured for ±15 V outputs, the difference |VPOS − VNEG| is guaranteed ≤ ±50 mV across –10°C to 85°C and 10–90% load conditions - ensuring stable differential source driver operation critical for E Ink grayscale fidelity.

Can the TPS65180BRGZR drive a 9.7-inch E Ink Vizplex panel?

Yes, the TPS65180BRGZR is explicitly qualified for 9.7-inch E Ink Vizplex panels. Its ±15 V/120 mA LDOs supply source drivers, +22 V/10 mA and –20 V/12 mA charge pumps power gate drivers, and the programmable VCOM driver (–0.3 V to –2.5 V) handles backplane bias - meeting all power requirements specified in the E Ink Vizplex datasheet.

What is the role of the TS pin on the TPS65180BRGZR?

TS is the thermistor input pin on the TPS65180BRGZR. It connects to a 10-kΩ NTC thermistor and 43-kΩ linearization resistor to measure E Ink panel temperature. The integrated ADC provides ±1°C accuracy from 0°C to 50°C, enabling firmware to adapt display waveforms and prevent thermal damage during extended operation.

Does the TPS65180BRGZR support I²C-based power sequencing?

Yes, the TPS65180BRGZR supports full I²C-based power sequencing via PWR_SEQ0–PWR_SEQ3 registers. Engineers can define custom startup and shutdown orders for all rails (CP1, CP2, LDO1, LDO2, VCOM), preventing panel latch-up and ensuring reliable initialization - a requirement for EPSON S1D13522 and OMAP-based e-reader platforms.
