Product details
Overview
TPS389006007RTER 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 to 5.5 V supply range, and active-low open-drain NIRQ output-designed for safety-critical power monitoring in medical robotics and industrial motor drives.
For engineers reviewing the TPS389006007RTER datasheet, TPS389006007RTER pinout, TPS389006007RTER application, or TPS389006007RTER equivalent, this page delivers verified functional safety parameters (SIL-3 hardware capability), real-time ADC readouts (125 ksps, 5–20 mV resolution), programmable glitch immunity (0.1 µs to 102.4 µs), sequence logging timestamp accuracy (±5%), and remote-sense-enabled core rail monitoring.
Technical Context
The TPS389006007RTER implements six independent SVS channels with dual-mode (LF/HF) monitoring, each configurable via I²C for overvoltage, undervoltage, or window detection. Its internal trimmed resistor dividers eliminate external threshold-setting components, enabling ±6 mV accuracy without calibration overhead.
It integrates an 8-bit ADC for real-time voltage readouts, CRC/PEC error checking on I²C transactions, and synchronized sequence logging across multiple devices via the SYNC pin-supporting rail tagging during power-up/down with 50 µs timestamp resolution and 4 s maximum timeout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | 6 independent voltage monitor inputs with 2 dedicated remote sense pins (RS_1/2) for PCB trace drop compensation on high-current rails. |
| Threshold Accuracy | ±6 mV (0.2 V–1.0 V range, –40°C to +125°C), enabling precise supervision of low-voltage SoC cores with narrow tolerance margins. |
| I²C Interface | Up to 1 MHz Fast Mode Plus support with PEC/CRC validation, allowing secure register access and fault reporting in safety-critical systems. |
| Supply Range | 2.5 V to 5.5 V VDD operation-compatible with common logic rails and DC/DC outputs without level-shifting. |
| Quiescent Current | 200 µA in idle mode (ACT = Low), minimizing standby power in always-on industrial control subsystems. |
| Package | 16-pin WQFN (RTE), 3 mm × 3 mm footprint-optimized for space-constrained PCB layouts in robotics and server switch modules. |
| Functional Safety | SIL-3 compliant per IEC 61508; includes built-in BIST, sequence/fault logging, and hardware-level fault detection coverage. |
Pinout & Package
TPS389006007RTER is housed in a thermally enhanced 16-pin WQFN package (RTE) with exposed thermal pad (Pin 17, GND). The package supports reflow soldering and provides low junction-to-board thermal resistance (17.2 °C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| MON1–MON6 | Voltage monitor inputs | Accept 0.2 V–5.5 V monitored rail voltages; MON1/MON2 share RS_1/2 for remote sensing of core supply drops. |
| RS_1/2 | Remote sense input | Enables differential measurement between local and remote points-critical for accurate core rail supervision under high load current. |
| NIRQ | Active-low open-drain interrupt | Asserts on UV/OV/window faults; requires external pull-up; compatible with wired-OR reset bus architectures. |
| SCL / SDA | I²C clock/data lines | Support up to 1 MHz communication; open-drain with internal weak pull-downs; require external 10 kΩ pull-ups to VDD or host logic rail. |
| ACT / SLEEP | Enable/control inputs | ACT (active-high) enables monitoring; SLEEP (active-low) enters low-power state; both trigger sequence logging timestamps. |
| SYNC | Multi-device synchronization | Coordinates rail tagging across multiple TPS389006 units-enables deterministic power sequencing in multi-rail systems. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable glitch immunity | I²C-configurable deglitch filter (0.1 µs–102.4 µs) eliminates false resets from transient noise without external RC networks. |
| Real-time voltage readout | Built-in 8-bit ADC (125 ksps, 5–20 mV LSB) provides continuous rail telemetry-supports redundancy verification against comparator thresholds. |
| Sequence logging | Timestamped ON/OFF events (±5% accuracy, 50 µs resolution) with cross-device SYNC coordination-validates power-up order in SIL-3 systems. |
| Auto-mask fault suppression | Configurable per-channel masking during ACT/SLEEP transitions-prevents spurious interrupts during known power transients. |
| Internal threshold resistors | Factory-trimmed divider network removes need for external resistors-guarantees ±6 mV accuracy without layout-dependent tolerances. |
Applications
| Medical Robotics | Industrial Motor Drives |
|---|---|

Use Scenario: Real-time supervision of FPGA, MCU, and gate driver supply rails during surgical robot actuation sequences. IC Role / Device Role / Timing Role: Six-channel window supervisor with remote sense on motor controller core rail; triggers NIRQ to halt motion if VDD falls below 2.48 V or exceeds 5.5 V. Use Value: Prevents unsafe actuator movement by detecting sub-100 µs voltage excursions with ±6 mV accuracy and 25 µs fault-to-NIRQ latency. |
Use Scenario: Monitoring isolated DC/DC outputs powering IGBT gate drivers and position encoder interfaces. IC Role / Device Role / Timing Role: Dual remote sense (RS_1/2) compensates for 80 mV IR drop across 200 mm PCB traces feeding 15 A motor phases. Use Value: Ensures gate driver enable only when core voltage remains within ±1.5% window-eliminating shoot-through risk from trace-induced droop. |
| Server Switch Power Systems | Automated Test Equipment (ATE) |
|
Use Scenario: Coordinating power sequencing across 12-V, 3.3-V, and 1.2-V rails in high-density Ethernet switch ASICs. IC Role / Device Role / Timing Role: SYNC pin synchronizes TPS389006007RTER units across multiple voltage domains; logs timestamped rail turn-on order. Use Value: Validates compliance with ASIC power-on requirements (e.g., 1.2-V core before 3.3-V I/O) using 50 µs-resolution sequence logging. |
Use Scenario: Ensuring stable bias conditions during precision analog stimulus generation in semiconductor test handlers. IC Role / Device Role / Timing Role: I²C-programmable thresholds (5 mV steps) adapt to varying DUT supply tolerances; ADC readouts verify rail stability pre-test. Use Value: Reduces test aborts by 92% versus fixed-threshold supervisors-detecting 30 mV drift in 1.8-V analog reference before DAC output corruption. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar multichannel voltage monitoring applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS389005007RTER | 5-channel version; identical package, accuracy, and I²C features-but lacks MON6 and one remote sense path. | Suitable for 5-rail systems where sixth channel is unused; retains full SIL-3 compliance and sequence logging. | Select when BOM cost reduction is prioritized and system has ≤5 monitored rails; no PCB change required. |
| MAX6816GWE+T | Quad-channel non-I²C supervisor; fixed thresholds, no ADC or remote sense; ±1.5% accuracy at 25°C (degrades to ±3% at 125°C). | Used in non-safety-critical industrial controls where SIL-3 is not mandated and rail count is ≤4. | Choose only for legacy designs requiring pin-compatible replacement without firmware updates; lacks sequence logging and PEC. |
Compared with TPS389006007RTER, the TPS389005007RTER preserves all safety and timing features but reduces channel count, while the MAX6816GWE+T sacrifices programmability, accuracy, and functional safety certification for lower unit cost in less demanding applications.
