Product details
Overview
TL7712ACDE4 from Texas Instruments is a precision supply-voltage supervisor IC designed as a reset controller for 12-V microprocessor and memory systems. It features a nominal 10.8-V threshold voltage (VIT−), 35-mV hysteresis, externally adjustable reset pulse duration via CT pin, temperature-compensated 2.53-V reference output, and operates across 3.5 V to 18 V supply range.
For engineers reviewing the TL7712ACDE4 datasheet, TL7712ACDE4 pinout, TL7712ACDE4 application, or TL7712ACDE4 equivalent, this device serves critical power-on and undervoltage reset generation in industrial control units, embedded instrumentation, and 12-V logic subsystems requiring stable, noise-immune reset assertion with defined timing.
Technical Context
The TL7712ACDE4 implements a dual-threshold comparator architecture with internal temperature-compensated bandgap reference, enabling precise 10.8-V (±0.2 V) undervoltage detection at the SENSE input. Its delay timer uses an external capacitor on CT to generate a user-defined reset pulse (0.65–2.6 ms typical with 0.1 µF).
It provides complementary open-collector RESET and RESET outputs, supports direct VCC-sense or resistor-divider configurations, and maintains functional integrity down to 3.5 V supply while tolerating up to 20 V transient stress per absolute maximum ratings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIT− Threshold | 10.6 V to 11.0 V (guaranteed 10.8 V typ); sets precise 12-V rail undervoltage trip point |
| Hysteresis | 35 mV; prevents chatter during slow-rising/falling supply transitions |
| Reference Voltage | 2.48 V to 2.58 V (2.53 V typ); stable, low-drift source for external sensing or calibration |
| Reset Pulse Duration | 0.65–2.6 ms (with 0.1 µF CT); ensures sufficient system initialization time before release |
| Supply Range | 3.5 V to 18 V; supports wide-input industrial and legacy 12-V systems |
| Operating Temp | 0 °C to 70 °C (AC grade); validated for commercial-temperature embedded applications |
| Output Type | Open-collector RESET and RESET; enables flexible pull-up/pull-down and wired-OR interfacing |
Pinout & Package
TL7712ACDE4 is housed in an 8-pin SOIC (D) package measuring 4.90 mm × 3.91 mm, with Gull-wing leads and RoHS-compliant NiPdAu finish. The package supports standard surface-mount reflow (MSL Level-1, 260 °C peak).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| REF (Pin 1) | Reference output | Provides stable 2.53-V reference for external divider or sensor biasing |
| RESIN (Pin 2) | Reset input | Manual reset trigger: active-low asynchronous override of automatic reset |
| CT (Pin 3) | Timing capacitor connection | Sets reset pulse width: td = 1.3×10⁴ × CT (e.g., 1.3 ms with 0.1 µF) |
| GND (Pin 4) | Ground reference | Analog and digital return; must be short-connected to decoupling capacitors' ground pads |
| RESET (Pin 5) | Inverted reset output | Active-low open-collector signal; requires external pull-up for logic-high state |
| RESET (Pin 6) | Non-inverted reset output | Active-high open-collector signal; requires external pull-up for logic-high state |
| SENSE (Pin 7) | Supply monitoring input | Monitors regulated 12-V rail directly or via resistor divider to detect VIT− |
| VCC (Pin 8) | Power supply input | Primary supply input (3.5–18 V); powers internal circuitry and reference |
Key Features
| Feature | Design Value |
|---|---|
| Externally adjustable reset timeout | Capacitor-programmable delay (0.65–2.6 ms typical) eliminates fixed-timing constraints |
| Precision 10.8-V threshold | Guaranteed ±0.2 V tolerance over temperature ensures reliable 12-V rail supervision |
| Temperature-compensated reference | 2.53-V output varies ≤16 mV from –40 °C to +85 °C; usable for calibration or biasing |
| Complementary reset outputs | Simultaneous active-high and active-low signals simplify interface to diverse MCU reset inputs |
| Wide operating supply range | 3.5 V to 18 V operation supports brown-out immunity across varying input conditions |
Applications
| Industrial PLC I/O Module | 12-V Embedded Instrumentation |
|---|---|
Use Scenario: Monitors 12-V DC power rail in programmable logic controller backplane modules subject to load transients and thermal cycling. IC Role / Device Role / Timing Role: Supervises VCC and asserts synchronized reset to FPGA and microcontroller upon undervoltage events. Use Value: Prevents metastability and corrupted register states during 12-V rail sags below 10.6 V, ensuring deterministic boot recovery. |
Use Scenario: Integrated into handheld test equipment powered by regulated 12-V wall adapters with variable line impedance. IC Role / Device Role / Timing Role: Generates 1.3-ms reset pulse after power-on and holds reset during brief dips caused by switching loads. Use Value: Eliminates spurious startup behavior by guaranteeing minimum reset assertion time independent of supply ramp rate. |
| Legacy 12-V Memory Subsystem | Automotive Body Control Unit (12-V) |
Use Scenario: Used in industrial memory expansion cards where 12-V supply feeds SRAM and CPLD logic. IC Role / Device Role / Timing Role: Detects undervoltage on memory VCC and asserts both RESET and RESET to coordinate power sequencing. Use Value: Ensures memory contents remain valid during brown-out by holding reset until supply stabilizes above 10.8 V + 35 mV hysteresis. |
Use Scenario: Supervises 12-V battery-derived supply in non-safety-critical body electronics (e.g., mirror control, lighting). IC Role / Device Role / Timing Role: Provides robust reset initiation during cold-crank (low-battery) events without false triggering from ripple. Use Value: Delivers noise-immune supervision using REF-based divider and CT-filtered timing, meeting automotive EMC requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar supply-voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL7712ACP | Same electrical specs; PDIP-8 package (9.81 mm × 6.35 mm), through-hole mounting, no MSL rating | Preferred for prototyping, manual assembly, or legacy board designs requiring DIP footprint | Select TL7712ACP when through-hole assembly or socket-based validation is required |
| TPS3808G12DBVR | Fixed 12-V threshold, 200-ms min reset pulse, higher accuracy (±0.5%), lower quiescent current (12 µA) | Better suited for ultra-low-power battery-backed systems; lacks adjustable timing and REF output | Choose TPS3808G12DBVR for modern low-IQ designs where fixed long-duration reset suffices |
Compared with TL7712ACP and TPS3808G12DBVR, TL7712ACDE4 uniquely combines adjustable reset timing, a buffered reference output, and SOIC packaging-making it optimal for cost-sensitive, production-ready 12-V embedded systems needing design flexibility and proven manufacturability.

FAQ
What is the exact undervoltage threshold voltage of TL7712ACDE4?
The TL7712ACDE4 has a guaranteed negative-going input threshold voltage (VIT−) of 10.6 V to 11.0 V at 25 °C, with 10.8 V typical. This value is specified for the AC grade (0 °C to 70 °C) and applies directly to the SENSE pin when monitoring a 12-V rail. Hysteresis of 35 mV ensures clean transition recovery.
How do I configure TL7712ACDE4 for a 12-V supply monitoring application?
To monitor a 12-V supply with TL7712ACDE4, connect VCC to the 12-V rail, tie SENSE directly to VCC (for direct sensing), place a 0.1-µF capacitor between CT and GND for ~1.3-ms reset pulse, and use 10-kΩ pull-up resistors on RESET and RESET outputs. REF may remain unused or serve as a local 2.53-V reference.
Does TL7712ACDE4 provide both active-high and active-low reset outputs?
Yes, TL7712ACDE4 provides two complementary open-collector reset outputs: RESET (Pin 6, active-high) and RESET (Pin 5, active-low). Both require external pull-up resistors. This dual-output architecture simplifies interface to MCUs or FPGAs that accept either polarity reset signal.
What package type and lead finish does TL7712ACDE4 use?
TL7712ACDE4 uses an 8-pin SOIC (D) package (4.90 mm × 3.91 mm) with NiPdAu (NIPDAU) lead finish, RoHS compliant, and MSL Level-1 rated for unlimited floor life at ≤30 °C/60% RH. It is supplied in tube packaging (75 units per tube).
Can TL7712ACDE4 operate from a 5-V supply?
No - TL7712ACDE4 is optimized for 12-V systems and specifies a 10.8-V threshold. For 5-V supervision, TI recommends TL7705A (4.55-V threshold). While TL7712ACDE4's supply range is 3.5 V to 18 V, its SENSE threshold remains fixed at ~10.8 V; applying 5 V to SENSE will never trigger reset assertion.
