Product details

Overview

TPS389006ADJRTER from Texas Instruments is a SIL-3 compliant six-channel I²C-programmable window voltage supervisor with two remote sense inputs, ±6 mV threshold accuracy over –40°C to +125°C, 2.5 V–5.5 V supply range, and active-low open-drain NIRQ output-designed for safety-critical power monitoring in medical robotics and industrial motor drivers.

For engineers reviewing the TPS389006ADJRTER datasheet, TPS389006ADJRTER pinout, TPS389006ADJRTER application, or TPS389006ADJRTER equivalent, this page delivers verified functional safety parameters (SIL-3 hardware capability), real-time ADC readouts (125 ksps, 5–20 mV resolution), I²C-configurable glitch immunity (0.1 µs–102.4 µs), and remote-sense–enabled core rail monitoring for high-current SoC power domains.

Technical Context

The TPS389006ADJRTER implements six independent voltage monitor channels with dual-mode (LF/HF) detection, each configurable via I²C for overvoltage, undervoltage, or window supervision. Its internal trimmed resistor dividers eliminate external threshold-setting components, enabling ±6 mV accuracy without resistor tolerance drift compensation.

It integrates a built-in 8-bit ADC for real-time voltage readouts, cyclic redundancy checking (CRC) and packet error checking (PEC) on I²C transactions, sequence logging with timestamping (±5% accuracy, 50 µs resolution), and SYNC-pin–based multi-device rail tagging-enabling coordinated sequencing with TI's TPS38700 for full SIL-3 system compliance.

Key Specifications

Parameter	Value and Actual Design Meaning
Channels	6 independent voltage monitor inputs with 2 remote sense terminals (RS_1/2) for PCB trace drop compensation on high-current rails.
Threshold Accuracy	±6 mV over –40°C to +125°C-enables reliable supervision of sub-1 V core supplies with narrow tolerance margins.
Supply Range	2.5 V to 5.5 V-supports direct connection to common intermediate rails (3.3 V, 5 V) without level-shifting.
I²C Interface	Up to 1 MHz Fast Mode Plus-enables dynamic reconfiguration of thresholds, deglitch filters, and interrupt masks during operation.
NIRQ Output	Active-low open-drain with <100 mV VOL at 5 mA sink-directly drives MCU reset or DC/DC enable pins across logic families.
Quiescent Current	200 µA in idle mode-minimizes standby power impact in always-on safety monitoring systems.
Package	16-pin WQFN (3 mm × 3 mm, 0.5 mm pitch)-enables high-density placement near critical power rails with low thermal resistance (RθJB = 17.2 °C/W).

Pinout & Package

TPS389006ADJRTER is housed in a 16-pin WQFN package (3 mm × 3 mm, 0.5 mm pitch) with exposed thermal pad (Pin 17, GND). The package supports automated optical inspection and provides low junction-to-board thermal resistance for sustained operation at 125°C ambient.

Pin/Terminal	Circuit Role	Design Meaning
MON1–MON6	Input	Independent voltage monitor channels; MON1 and MON2 share RS_1/2 for remote sensing of core rail voltage drop.
RS_1/2	Input	Remote sense input shared by MON1/MON2-enables Kelvin sensing to cancel PCB IR drop in high-current applications.
VDD	Power	Main supply input (2.5–5.5 V); powers internal reference, ADC, and digital core-no external bypass capacitor required.
GND (Pins 6 & 17)	Ground	Dual ground connections: Pin 6 (signal ground), Pin 17 (exposed thermal pad, must be soldered to PCB ground plane).
NIRQ	Output	Active-low open-drain interrupt-asserts on UV/OV fault, BIST failure, or sequence timeout; requires external pull-up.
SCL / SDA	I/O	I²C clock/data lines supporting Standard (100 kHz), Fast (400 kHz), and Fast Mode Plus (1 MHz) protocols with PEC support.
ACT / SLEEP	Input	Asynchronous control pins: ACT enables device operation; SLEEP enters low-power state with configurable wake-up behavior.
SYNC	I/O	Multi-device synchronization pin-coordinates rail tagging and sequence logging across multiple TPS389006 units on one board.

Key Features

Feature	Design Value
SIL-3 Hardware Capability	Meets IEC 61508 systematic and hardware safety integrity requirements-enables use in medical robotics and industrial safety PLCs without additional component-level FMEDA.
Internal Threshold Resistors	Eliminates need for external resistor networks-reduces BOM count, layout area, and accuracy degradation from resistor tolerance and temperature drift.
I²C-Configurable Glitch Immunity	Adjustable deglitch filter (0.1 µs–102.4 µs per channel)-suppresses transient-induced false resets without external RC networks.
Built-in 8-bit ADC	Real-time voltage readouts (0.2–5.5 V range, 5/20 mV LSB) with 125 ksps sampling-provides redundant verification alongside comparator-based fault detection.
Sequence Logging with Timestamping	Records rail power-on/off events with ±5% timestamp accuracy and 50 µs resolution-enables root-cause analysis of power sequencing failures.

Equivalent & Alternatives

The following parts are listed as comparable options for similar multichannel voltage supervision applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TPS389005ADJRTER	5-channel version (no MON6), identical accuracy, package, and I²C feature set-lacks sixth monitor channel and associated register space.	Suitable where only five rails require supervision; retains full SIL-3 compliance and remote sense capability on MON1/MON2.	Select when BOM optimization is prioritized over future-proofing for sixth rail expansion.
MAX25210ATPA/VY+	6-channel automotive-grade supervisor (AEC-Q100 Grade 0), ±15 mV accuracy, SPI interface, no remote sense-higher threshold tolerance, different serial protocol.	Targeted at automotive ADAS ECUs; lacks remote sensing and I²C PEC/CRC, but offers extended temperature range (–40°C to +150°C).	Choose for automotive environments requiring AEC-Q100 qualification, accepting trade-off in accuracy and interface flexibility.

Compared with TPS389005ADJRTER and MAX25210ATPA/VY+, the TPS389006ADJRTER uniquely combines six-channel supervision, ±6 mV accuracy, remote sense, I²C PEC/CRC, and SIL-3 hardware certification-making it the only option for high-integrity industrial robotics requiring both precision and functional safety assurance.

FAQ

What is the functional safety certification status of the TPS389006ADJRTER?

The TPS389006ADJRTER is developed to meet IEC 61508 requirements for functional safety applications, with documented systematic capability and hardware capability up to SIL 3. It includes integrated features such as CRC, PEC, sequence logging, and BIST to support safety architecture implementation-but final system-level SIL certification remains the responsibility of the end-equipment designer.

How does the remote sense functionality work on the TPS389006ADJRTER?

The TPS389006ADJRTER uses the RS_1/2 pin to perform Kelvin sensing on MON1 and MON2 inputs, measuring voltage directly at the load to compensate for IR drop across PCB traces. This enables ±6 mV accuracy on high-current rails like FPGA cores, where trace resistance would otherwise degrade supervision fidelity-without requiring external op-amps or differential amplifiers.

Can the TPS389006ADJRTER monitor voltages below 0.2 V or above 5.5 V?

No. The TPS389006ADJRTER specifies a valid MONx input voltage range of 0.2 V to 5.5 V per electrical characteristics. Voltages below 0.2 V fall outside guaranteed operation and may trigger undefined behavior; voltages above 5.5 V exceed absolute maximum ratings and risk permanent damage. External scaling resistors are not supported-the device relies on internal precision dividers.

What I²C address options are available for the TPS389006ADJRTER?

The TPS389006ADJRTER supports eight I²C addresses (0x30–0x37) selected via the ADDR pin using external resistors (5.36 kΩ to 80.6 kΩ). Each resistor value maps to a unique 7-bit address, enabling up to eight devices on the same bus-critical for multi-rail systems requiring individual configuration without address conflict.

Does the TPS389006ADJRTER require external passive components for basic operation?

No external resistors are required to set voltage thresholds-the TPS389006ADJRTER integrates precision trimmed dividers. A 1-µF VDD bypass capacitor is recommended but not mandatory for low-noise operation. Pull-up resistors on SCL/SDA/NIRQ (10 kΩ typical) and optional MON input bypass caps (1–10 nF) are the only external passives needed for robust deployment.
