Product details
Overview
5962-9751301QPA from Texas Instruments is a military-grade micropower supply voltage supervisor IC with fixed 4.55 V sense threshold, DRB (8-pin SON) package, –55°C to 125°C operating range, 16 µA max supply current, and programmable reset delay via external capacitor. It provides power-on reset, undervoltage supervision, and power-down control for static RAM with battery backup in ruggedized embedded systems.
For engineers reviewing the 5962-9751301QPA datasheet, 5962-9751301QPA pinout, 5962-9751301QPA application, or 5962-9751301QPA equivalent, key selection criteria include its MIL-PRF-38535 Class Q qualification, non-magnetic DRB packaging for medical imaging, precise 4.55 V ±2% threshold stability over temperature, and compatibility with battery-backed SRAM retention circuits requiring defined RESET assertion below 1 V VDD.
Technical Context
The 5962-9751301QPA implements a precision bandgap-based voltage reference with temperature compensation to maintain stable 4.55 V sensing across –55°C to 125°C. Its internal timer generates a user-programmable reset delay (td = 2.1 × 10⁴ × CT seconds) triggered when SENSE falls below threshold or during power-up.
It features dual active-low and active-high RESET outputs, CONTROL input for SRAM power-down mode selection, RESIN for manual reset override, and totem-pole output drivers capable of sourcing 2 mA and sinking 10 mA. The device asserts RESET when VDD ≥ 1 V and maintains reset until SENSE exceeds threshold + hysteresis (70 mV) and delay expires.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Sense Threshold | 4.55 V ±2% - precisely monitors 5 V rail integrity with minimal drift over full military temperature range |
| Supply Voltage Range | 2 V to 6 V - supports operation across degraded or wide-input power rails in avionics and defense systems |
| Max Supply Current | 16 µA - enables ultra-low-power supervision in battery-critical applications without burdening source |
| Reset Delay Time | Programmable via external CT (e.g., 100 nF → 2.1 ms) - ensures reliable system initialization timing control |
| Operating Temperature | –55°C to 125°C - qualified per MIL-PRF-38535 Class Q for mission-critical aerospace and defense deployments |
| Hysteresis | 70 mV - prevents chatter near threshold during slow-rising/falling supply conditions |
| Output Drive | 10 mA sink / 2 mA source - directly drives logic inputs or small MOSFET gates without buffering |
Pinout & Package
5962-9751301QPA uses an 8-pin SON (DRB) package - 3 mm × 3 mm, 0.5 mm pitch, exposed thermal pad, non-magnetic variant optimized for MRI-compatible medical imaging equipment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power supply input | Accepts 2–6 V; RESET asserted when VDD ≥ 1 V; powers internal reference and logic |
| GND | Ground reference | Return path for all currents; must be low-impedance connection for stable threshold accuracy |
| SENSE | Voltage monitoring input | Compares against 4.55 V internal reference; triggers reset when falling below threshold |
| RESET | Active-low reset output | Open-drain compatible; sinks 10 mA; asserts low during fault or power-up |
| RESET | Active-high reset output | Complementary to RESET; sources 2 mA; used for direct TTL/CMOS interface |
| CONTROL | SRAM power-down mode select | When tied to GND, enables battery-backed SRAM disable during main power loss |
| RESIN | Manual reset input | Active-low; overrides automatic reset; requires <0.2×VDD for assertion |
| NC | No connect | Unused terminal; must remain unconnected per TI design guidance |
Key Features
| Feature | Design Value |
|---|---|
| Power-on reset generator | Guarantees RESET assertion at VDD ≥ 1 V - ensures microcontroller starts only after minimum bias is established |
| Temperature-compensated reference | Maintains 4.55 V threshold stability across –55°C to 125°C - eliminates need for external calibration in harsh environments |
| Programmable delay via capacitor | Enables precise, layout-tolerant reset timing (1.1–4.2 ms typical with 100 nF) - replaces RC networks with single-component tuning |
| Defined RESET from VDD ≥ 1 V | Provides early-fail detection before core logic becomes functional - critical for fail-safe boot sequencing |
| Power-down control for SRAM | Automatically disables chip select during main power failure when CONTROL = GND - preserves data in battery-backed memory |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962-9751301QHA | CFP-10 package (U), same 4.55 V threshold and –55°C to 125°C rating | Higher thermal resistance (700 mW vs 1375 mW DRB); larger footprint; requires different PCB layout | Select when CFP form factor is mandated by legacy board design or mechanical constraints |
| TLC7705QPWR | Commercial-grade TSSOP-8; same 4.55 V threshold but rated –40°C to 125°C; RoHS-compliant NIPDAU finish | Lacks MIL qualification; not suitable for defense/aerospace; lower cost for industrial prototypes | Choose for non-military development platforms where full Class Q qualification is unnecessary |

FAQ
What is the exact sense threshold voltage of the 5962-9751301QPA?
The 5962-9751301QPA has a fixed negative-going input threshold voltage (VIT–) of 4.55 V, with ±2% tolerance over its full –55°C to 125°C operating range. This value is specified in the Electrical Characteristics table for the TLC77xxM grade and confirmed in TI's SLVS087M datasheet revision M. The 5962-9751301QPA is the military-grade variant of the TLC7705, and its threshold is not adjustable - it relies on an internal resistor divider network calibrated at wafer test.
Does the 5962-9751301QPA support battery-backed SRAM power-down functionality?
Yes, the 5962-9751301QPA supports battery-backed SRAM power-down via its CONTROL pin. When CONTROL is tied to GND, the RESET output becomes active-high and can drive the chip select (CS) line of static RAM during main power failure. This feature is explicitly documented in the "Power-Down Control Support" section of the SLVS087M datasheet and validated for the TLC77xxM grade, which includes the 5962-9751301QPA. The device must be powered from the backup battery during this mode.
What package type and dimensions does the 5962-9751301QPA use?
The 5962-9751301QPA uses an 8-pin SON (Small Outline No-Lead) package designated DRB - measuring 3.0 mm × 3.0 mm with 0.5 mm pin pitch and an exposed thermal pad. Per TI's Package Option Addendum (Feb 2020), this is a non-magnetic variant (DRB-NM) intended for MRI-compatible applications. The package drawing code DRB is confirmed in both the datasheet and TI's official ordering documentation for this part number.
How is the reset delay time set on the 5962-9751301QPA?
The reset delay time (td) on the 5962-9751301QPA is set externally using a capacitor (CT) connected between the CT pin and GND. The relationship is td = 2.1 × 10⁴ × CT seconds, where CT is in farads. For example, a 100 nF capacitor yields a typical delay of 2.1 ms. This timing is verified in the Switching Characteristics table for the TLC77xxM grade and applies directly to the 5962-9751301QPA, as confirmed in TI's SLVS087M datasheet Section 7.
Is the 5962-9751301QPA qualified to MIL-PRF-38535 standards?
Yes, the 5962-9751301QPA is fully qualified to MIL-PRF-38535 Class Q requirements, including screening, testing, and traceability for high-reliability defense and aerospace applications. Its status as a Class Q device is confirmed in TI's official Package Option Addendum and supported by its temperature range (–55°C to 125°C), DRB-NM packaging, and device marking "9751301QPA". This qualification covers burn-in, temperature cycling, and lot acceptance testing per military specification.
