Product details
Overview
STM6717TZWY6F from STMicroelectronics is a dual ultra-low-voltage supervisor IC with push-button reset and open-drain active-low RST output, monitoring VCC1 (factory-trimmed 4.63 V threshold) and VCC2 (3.08 V threshold), operating from –40 °C to +85 °C with 11 µA typical supply current and 13.2 ms power-up reset delay - used in set-top boxes and portable battery-powered systems.
For engineers reviewing the STM6717TZWY6F datasheet, STM6717TZWY6F pinout, STM6717TZWY6F application, or STM6717TZWY6F equivalent, key selection criteria include dual-supply monitoring capability, guaranteed RST state at VCC ≥ 0.8 V, SOT23-5 package compatibility, and manual reset timing behavior under industrial temperature conditions.
Technical Context
The device implements independent voltage comparators for VCC1 and VCC2 against factory-trimmed thresholds, with logic OR combining of fault conditions to assert RST. Reset assertion persists for trec (13.2/210/900 ms typ) after all monitored supplies exceed thresholds and MR returns high.
It features an internal 50 kΩ pull-up on MR, supports TTL/CMOS-level inputs, and guarantees valid RST output state when VCC1 or VCC2 ≥ 0.8 V - enabling reliable reset generation even during brown-out conditions common in battery-powered systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold | 4.63 V fixed (factory-trimmed); ensures precise power-on reset for 5 V rails |
| VCC2 Threshold | 3.08 V fixed (factory-trimmed); monitors 3.3 V auxiliary supply with ±1.5% accuracy over temp |
| Reset Delay (trec) | 13.2 ms typical; provides sufficient hold time for processor initialization sequences |
| Supply Current | 11 µA typ at 3.6 V; enables multi-year operation in coin-cell–powered standby circuits |
| Operating Temp | –40 °C to +85 °C; qualified for industrial-grade embedded applications |
| RST Output Type | Active-low open drain; requires external pull-up (e.g., 10 kΩ to VCC1) for system-level reset signaling |
| MR Input | Push-button compatible with internal 50 kΩ pull-up; no external debounce needed for momentary switch interface |
Pinout & Package
SOT23-5 (WY) package: 5-pin surface-mount, 1.3 mm × 2.9 mm footprint, 1.45 mm height, JEDEC MO-178 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - RST | Active-low open-drain reset output | Drives low on any fault (VCC1/VCC2 drop or MR assertion); requires external pull-up for logic-high state |
| 2 - VCC1 | Primary supply voltage input | Monitored at 4.63 V threshold; powers internal circuitry and serves as RST pull-up reference |
| 3 - VCC2 | Secondary supply voltage input | Monitored at 3.08 V threshold; enables dual-rail supervision without external components |
| 4 - MR | Manual reset input | Active-low push-button interface with internal 50 kΩ pull-up; debounced by design |
| 5 - VSS | Ground reference | Common return path for all internal comparators and logic; must be low-impedance |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent supply monitoring | Simultaneous VCC1 and VCC2 supervision eliminates need for two discrete supervisors |
| Guaranteed RST state at low VCC | Valid reset output asserted even when VCC1 or VCC2 ≥ 0.8 V - critical for brown-out resilience |
| Factory-trimmed precision thresholds | ±1.5% threshold accuracy over temperature avoids calibration overhead in production |
| Ultra-low quiescent current | 11 µA typical enables integration into always-on subsystems without battery drain penalty |
| Open-drain RST with flexible pull-up | Supports mixed-voltage systems via user-selectable pull-up voltage (e.g., to 1.8 V, 3.3 V, or 5 V rail) |
Applications
| Set-Top Box Power Management | Portable Medical Monitor |
|---|---|
Use Scenario: Supervises main 5 V and 3.3 V rails during cold start and brown-out events in cable/satellite STBs. IC Role / Device Role / Timing Role: Dual-supply monitor asserting open-drain RST to SoC reset pin; holds reset until both rails stabilize for ≥13.2 ms. Use Value: Prevents firmware corruption by ensuring CPU only exits reset after stable dual-rail operation - validated per EN 300 468 compliance requirements. | Use Scenario: Monitors battery-backed 3.3 V MCU supply and 1.8 V sensor interface rail in handheld ECG devices. IC Role / Device Role / Timing Role: Generates clean, glitch-free reset pulse on power-up or button press; operates reliably down to 0.8 V VCC for low-battery detection. Use Value: Enables fail-safe boot sequence with <11 µA standby draw - extending single-CR2032 battery life beyond 24 months in sleep mode. |
| Industrial Ethernet Gateway | Smart Home Hub Controller |
Use Scenario: Ensures deterministic reset of ARM Cortex-M7 processor and PHY IC during 24 V DC-to-3.3 V/5 V conversion transients. IC Role / Device Role / Timing Role: VCC1 monitors 5 V PoE-derived rail; VCC2 tracks isolated 3.3 V microcontroller supply; RST coordinates synchronized restart. Use Value: Eliminates race conditions between power rails and digital logic - meeting IEC 61000-4-2/4-4 immunity test pass criteria. | Use Scenario: Provides supervised startup for dual-core application processor (VCC1 = 1.1 V core, VCC2 = 3.3 V I/O) in voice-controlled hubs. IC Role / Device Role / Timing Role: Uses external resistor divider on RSTIN (not applicable to STM6717) - not used; relies on fixed VCC1/VCC2 thresholds for primary supervision. Use Value: Reduces BOM count by replacing discrete reset IC + voltage detector combo - lowering assembly cost by $0.12/unit at 100k volume. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS3808G18DBVR | Single-supply monitor (1.8 V threshold only); no VCC2 input; push-pull RST output | Requires external circuitry to supervise second rail; lacks native dual-threshold architecture | Select when only one supply needs monitoring and push-pull drive is preferred |
| MAX6816EUT+T | Single-channel push-button debouncer (no voltage monitoring); 5 V only; no reset delay option | Cannot replace voltage supervision function; only handles MR signal conditioning | Select only as MR front-end companion, not as functional replacement |
Compared with TPS3808G18DBVR and MAX6816EUT+T, STM6717TZWY6F uniquely integrates dual-rail voltage monitoring, factory-trimmed thresholds, and open-drain RST in SOT23-5 - eliminating external components required by alternatives to achieve equivalent system-level reset integrity.

FAQ
What is the minimum VCC voltage at which STM6717TZWY6F guarantees correct RST output state?
The device guarantees valid RST logic state when VCC1 or VCC2 is ≥ 0.8 V. Below this, output behavior is undefined. This specification enables robust reset assertion during brown-out conditions before full rail stabilization, supporting fail-safe boot in battery-powered applications where supply droop is common.
Can STM6717TZWY6F monitor a 1.2 V supply rail?
No - STM6717TZWY6F has fixed VCC1 (4.63 V) and VCC2 (3.08 V) thresholds; it cannot monitor 1.2 V directly. For sub-3 V rails, use STM6719/20/79/80 variants with RSTIN pin and 0.626 V internal reference, configured via external resistor divider to set custom thresholds down to ~0.63 V.
Is an external pull-up resistor required on the RST pin?
Yes - because RST is open-drain, a pull-up resistor (typically 10 kΩ to VCC1) is mandatory to establish a defined high state when reset is inactive. Without it, RST floats and cannot drive high, risking undefined processor behavior during normal operation.
Does STM6717TZWY6F support delayed manual reset via capacitor?
No - delayed manual reset (MRC pin) is exclusive to STM6777/78/79/80 variants. STM6717TZWY6F uses standard MR input with immediate assertion; delay must be implemented externally using RC networks or dedicated timer ICs if required.
