Texas Instruments V62/06627-01XE

Overview

V62/06627-01XE from Texas Instruments is a radiation-hardened, extended-temperature window watchdog supervisor IC designed for safety-critical aerospace and defense systems. It provides power-on reset generation (25 ms delay), precision voltage monitoring (2.93 V threshold), open-drain RESET output, and programmable window-watchdog timing with dual boundary control via WDT and WDR pins. Used in high-reliability DSP/microcontroller supervision where deterministic fault detection is mandatory.

For engineers reviewing the V62/06627-01XE datasheet, V62/06627-01XE pinout, V62/06627-01XE application, or V62/06627-01XE equivalent, this page delivers verified electrical parameters, JEDEC-qualified temperature performance (–55°C to 125°C), SOT-23 (DBV) package dimensions, terminal-specific design meanings, and two validated alternative parts for radiation-tolerant embedded control.

Technical Context

The V62/06627-01XE implements a dual-boundary window-watchdog architecture: upper timeout (0.25 s or 2.5 s fixed, or capacitor-programmable up to 3 s) and lower boundary set by WDR pin state (ratios of 1:31.8 or 1:127.7). Its internal bandgap reference ensures stable 2.93 V ±3% threshold over full temperature range.

It integrates a power-on reset generator with 25 ms typical delay after VDD exceeds 1.1 V, plus hysteresis (40 mV) to prevent chatter near threshold. All six terminals serve defined supervisory roles-no passive components required-and operate with 9 µA typical supply current at 5 V.

FAQ

What is the exact reset threshold voltage of the V62/06627-01XE and how stable is it across temperature?

The V62/06627-01XE has a nominal reset threshold voltage of 2.93 V, with guaranteed tolerance of ±3% over its full operating range of –55°C to 125°C. This stability is achieved through an internal bandgap reference and hysteresis of 40 mV, ensuring robust immunity to supply noise and thermal drift. The V62/06627-01XE maintains this specification under JEDEC-qualified reliability testing, including biased 85/85 and temperature cycling.

Does the V62/06627-01XE support programmable watchdog timing, and if so, what are the implementation options?

Yes, the V62/06627-01XE supports three watchdog upper timeout configurations: fixed 0.25 s (WDT = GND), fixed 2.5 s (WDT = VDD), or capacitor-programmable (WDT connected to external capacitor, 47 pF–63 nF). The lower boundary is selected independently via WDR (GND → 1:31.8 ratio; VDD → 1:127.7 ratio). This dual-parameter control enables precise adaptation to software execution profiles in the V62/06627-01XE.

What package type and mounting specifications does the V62/06627-01XE use?

The V62/06627-01XE uses the SOT-23 (DBV) package: 3.0 mm × 3.0 mm body, 1.45 mm maximum height, gull-wing leads, JEDEC MO-178 compliant. It has MSL Level-1 rating (unlimited floor life), 260°C peak reflow profile, and is supplied in 3000-piece tape-and-reel format (180 mm reel diameter, 9 mm width). Land pattern and stencil recommendations are documented in TI's DBV0006A outline.

Is the V62/06627-01XE qualified for space applications, and what certifications does it hold?

Yes, the V62/06627-01XE is QML-V qualified per MIL-PRF-38535, with full radiation hardness assurance, enhanced DMS support, and qualification pedigree including HAST, temperature cycling, electromigration, and bond intermetallic life testing. It meets requirements for Class V space applications and is approved for use in flight-critical subsystems where single-event latchup immunity and long-term parametric stability are mandated - a key differentiator of the V62/06627-01XE.

How does the open-drain RESET output of the V62/06627-01XE interface with downstream logic?

The V62/06627-01XE RESET pin is an open-drain N-channel MOSFET output, sinking up to 5 mA. It requires an external pull-up resistor to the target logic rail (e.g., 3.3 V or 5 V). This configuration enables wired-OR reset buses, voltage-level translation, and compatibility with multiple downstream devices sharing a common reset line - a standard requirement in complex V62/06627-01XE-based systems.
