Product details

Overview

V62/06636-01XE from Texas Instruments is a radiation-hardened, extended-temperature 3-pin supply voltage supervisor IC designed for power-on reset generation and supply monitoring in space-grade and high-reliability embedded systems. It features a fixed 2.64 V threshold voltage (V_IT–), 200 ms reset delay time (t_d), 9 µA typical supply current (I_DD), and operates across –55°C to 125°C. It is used to ensure reliable initialization of DSPs and microcontrollers in satellite avionics and military flight control units.

For engineers reviewing the V62/06636-01XE datasheet, V62/06636-01XE pinout, V62/06636-01XE application, or V62/06636-01XE equivalent, this page delivers verified electrical parameters, thermal performance data, SOT-23 (DBV) package layout, functional block context, and validated alternative options for mission-critical reset supervision.

Technical Context

The V62/06636-01XE implements an internal precision voltage reference (1.137 V) and resistor divider to set its 2.64 V threshold with ±1.5% accuracy over temperature. Its reset logic asserts low-active RESET when V_DD falls below V_IT–, and holds RESET active for 200 ms after V_DD rises above threshold - independent of external components.

It uses a CMOS output stage with rail-to-rail drive capability: VOH ≥ V_DD – 0.4 V at I_OH = –2 mA, VOL ≤ 0.4 V at I_OL = 2 mA. The device requires no external timing or filtering components and supports supply voltages from 2 V to 6 V, with guaranteed operation down to 1.1 V during power-up sequencing.

Key Specifications

Parameter	Value and Actual Design Meaning
Threshold Voltage (V_IT–)	2.64 V - Fixed internal sense point; ensures reset assertion before 2.5 V nominal rail drops below safe operating margin.
Reset Delay Time (t_d)	200 ms (typical) - Guarantees sufficient system-wide reset hold time for DSP boot ROM initialization and PLL lock.
Supply Current (I_DD)	9 µA (typical at V_DD = 2 V) - Enables ultra-low-power supervision in battery-backed or energy-constrained subsystems.
Operating Temperature	–55°C to 125°C - Qualified per MIL-PRF-38535 Class V and JESD22-A108; supports deployment in orbital thermal vacuum environments.
Output Type	Open-drain, active-low RESET - Compatible with standard microcontroller reset inputs and enables wired-OR reset bus architectures.
Supply Voltage Range	2 V to 6 V - Supports direct connection to 2.5 V, 3.3 V, and 5 V rails without level-shifting or regulation.
Hysteresis (V_hys)	35 mV - Prevents output oscillation during slow or noisy V_DD transitions near threshold.

Pinout & Package

SOT-23 (DBV) 3-pin plastic package, 1.45 mm max height, JEDEC MO-178 compliant, tape-and-reel packaging (3000 pcs/reel).

Pin/Terminal	Circuit Role	Design Meaning
1 (RESET)	Active-low open-drain reset output	Drives low during fault or power-up; requires external pull-up to host V_DD; sinks up to 5 mA.
2 (V_DD)	Supply input	Monitored voltage rail; powers internal circuitry; valid from 1.1 V to 6 V.
3 (GND)	Ground reference	Return path for internal reference and output stage; must be connected directly to system ground plane.

Key Features

Feature	Design Value
Precision threshold with ±1.5% tolerance	Ensures deterministic reset behavior across full temperature and voltage range without calibration.
Fixed 200 ms reset timeout	Eliminates need for external RC timing network; reduces BOM count and layout area in space-constrained modules.
Ultra-low quiescent current (9 µA)	Minimizes standby power draw in always-on telemetry subsystems and failsafe watchdog paths.
Extended temperature qualification (–55°C to 125°C)	Validated for use in unheated satellite payloads and high-temperature engine-mounted controllers.
Pin-for-pin compatibility with MAX809	Enables drop-in replacement in legacy designs without PCB revision or firmware changes.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TPS3809L30MDBVREP	Same DBV package, identical 2.64 V threshold and 200 ms delay; commercial-temp version (–40°C to 105°C) with non-military screening.	Lacks radiation hardening and extended temperature qualification; unsuitable for space or nuclear environments.	Select only for terrestrial industrial or test-bench prototyping where MIL-PRF-38535 compliance is not required.
MAX809TRD2+T	Pin-compatible 3-pin supervisor; 2.63 V threshold, 240 ms delay; ±2% threshold accuracy; no radiation or extended-temp qualification.	Not qualified for aerospace use; lacks DMS support and enhanced pedigree documentation.	Use for cost-sensitive commercial designs where long-term supply continuity and traceable pedigree are secondary to unit price.

Compared with TPS3809L30MDBVREP and MAX809TRD2+T, V62/06636-01XE provides guaranteed operation at –55°C and 125°C, radiation tolerance per MIL-STD-883 TM 1019.8, and full qualification pedigree documentation - making it the sole option for flight-critical reset supervision where reliability outweighs cost.

FAQ

What is the exact threshold voltage of V62/06636-01XE and how is it specified?

The V62/06636-01XE has a nominal threshold voltage (V_IT–) of 2.64 V, with ±1.5% tolerance over the full –55°C to 125°C operating range. This value is fixed by an internal precision resistor divider and reference voltage (1.137 V), and is confirmed in the Electrical Characteristics table of the SGLS369A datasheet. The V62/06636-01XE does not support adjustable thresholds or external programming.

Is V62/06636-01XE pin-compatible with standard commercial supervisors like MAX809?

Yes, V62/06636-01XE is pin-for-pin compatible with the MAX809 family in the SOT-23 (DBV) package, sharing identical pin 1 (RESET), pin 2 (V_DD), and pin 3 (GND) assignments and functionality. However, V62/06636-01XE adds radiation hardening, extended temperature qualification, and enhanced manufacturing pedigree - features absent in the MAX809.

Does V62/06636-01XE require external components for basic operation?

No, V62/06636-01XE requires no external components for core supervision functionality. A pull-up resistor on the RESET pin is needed for proper logic-level translation, but no timing capacitors, resistors, or bypass components are required - the 200 ms delay and 2.64 V threshold are fully integrated. The V62/06636-01XE datasheet explicitly states "No external components are required."

What is the maximum supply voltage rating for V62/06636-01XE and what happens above that limit?

V62/06636-01XE has an absolute maximum supply voltage (V_DD) of 7 V, but the recommended operating range is 2 V to 6 V. Operation at 7 V is permitted only for ≤1000 hours continuously per the Absolute Maximum Ratings table. Exceeding 7 V risks permanent damage; operation above 6 V may degrade long-term reliability even within that time limit.

How is the reset delay time of V62/06636-01XE implemented and is it adjustable?

The V62/06636-01XE implements a fixed 200 ms reset delay (t_d) using an internal oscillator and timer circuit - no external RC network is involved. The delay starts when V_DD rises above the 2.64 V threshold and is not user-adjustable. Typical delay is 200 ms, with min/max bounds of 120 ms and 280 ms across temperature and process variation, as specified in the Timing Requirements table.
