Product details
Overview
ADPL62935SUK+T from Analog Devices is a low-voltage microprocessor supervisory IC in a 5-pin SOT23 package, monitoring VCC from +1.8V to +5.0V with a preprogrammed 2.93V reset threshold (suffix 'S'), 140ms minimum reset timeout, push-pull active-low RESET and active-high RESET outputs, and a debounced manual reset input. It ensures reliable µP initialization in brownout and power-up conditions for embedded controllers and portable equipment.
For engineers reviewing the ADPL62935SUK+T datasheet, ADPL62935SUK+T pinout, ADPL62935SUK+T application, or ADPL62935SUK+T equivalent, this page delivers verified electrical parameters, functional pin roles, real-world use cases, and validated alternative parts - all aligned to the official Analog Devices specification for -40°C to +125°C operation and RoHS-compliant SOT23-5 packaging.
Technical Context
The ADPL62935SUK+T implements a precision voltage monitor with hysteresis and an internal timer-based reset assertion logic. Its dual push-pull reset outputs (RESET and RESET) provide complementary signaling without external pull-ups, while the MR input features a 50kΩ internal pull-up and 100ns glitch rejection.
It guarantees valid reset state down to VCC = +1.0V and tolerates short negative VCC transients - critical for battery-powered systems where supply rails dip during load switching. The device requires no external components and operates across industrial temperature range (-40°C to +125°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.93V ±1.5% over -40°C to +125°C - sets precise brownout detection point for +3.3V systems |
| Reset Timeout Period | 140ms (min) - ensures µP remains held in reset long enough for stable clock and power rail settling |
| VCC Operating Range | +1.2V to +5.5V - supports operation during deep brownout and compatibility with 1.8V–5.0V logic domains |
| Reset Output Drive | Push-pull, 3.2mA sink at VCC ≥ 4.75V - eliminates need for external pull-up resistors on RESET/RESET lines |
| MR Input Logic | CMOS-compatible, 0.2×VCC low / 0.8×VCC high - enables direct interface with FPGA I/O or microcontroller GPIO |
| Supply Current | 7µA (typ) at +3.6V, -40°C to +85°C - enables ultra-low-power supervision in always-on battery backup circuits |
Pinout & Package
ADPL62935SUK+T is housed in a RoHS-compliant 5-pin SOT23-5 package (Analog Devices package code U5-1, outline 21-0057), with 0.95mm pitch, 2.9mm × 1.6mm footprint, and thermal resistance θJA = 140°C/W on a 4-layer board.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - RESET | Active-Low Push-Pull Reset Output | Drives µP reset pin low during VCC undervoltage or MR assertion; self-releases after 140ms timeout |
| 2 - GND | Ground Reference | Primary return path for VCC, MR, and reset outputs; must be low-impedance connection to system ground plane |
| 3 - RESET | Active-High Push-Pull Reset Output | Provides inverted reset signal for logic that requires active-high reset enable (e.g., some FPGAs or ASICs) |
| 4 - MR | Active-Low Manual Reset Input | Internally pulled up to VCC (50kΩ); momentary GND connection forces reset - no external debounce needed |
| 5 - VCC | Supply & Voltage Monitor Input | Power source and monitored rail; reset asserts when VCC falls below 2.93V; output valid down to 1.0V |
Key Features
| Feature | Design Value |
|---|---|
| Dual Complementary Reset Outputs | Simultaneous active-low RESET and active-high RESET eliminate level-shifting or inverters in mixed-logic systems |
| Guaranteed Reset Validity to VCC = +1.0V | Ensures deterministic reset behavior even during severe brownout - critical for non-volatile memory write protection |
| No External Components Required | Reduces BOM count, PCB area, and qualification effort - only decoupling capacitor needed per typical operating circuit |
| Immunity to Short Negative VCC Transients | Withstands ≤20µs, 100mV undershoot without spurious reset - improves robustness in noisy DC-DC converter environments |
| Industrial Temperature Range Support | Full functionality from -40°C to +125°C - qualified for automotive under-hood, industrial PLC, and outdoor embedded applications |
Applications
| Set-Top Box Power Management | Portable Medical Instrument Monitoring |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6326UT29D+T | Single active-low reset output; 2.93V threshold; 140ms timeout; 5-pin SOT23; max VCC = +5.5V | Lacks complementary RESET output - requires external inverter for active-high reset needs | Select when only one reset polarity is required and board space is constrained; identical timing and threshold accuracy |
| TPS3808G33DBVR | Single active-low reset; 3.08V threshold (T suffix); 200ms timeout; 5-pin SOT23; VCC range 0.8V–6.0V | Higher threshold (3.08V vs. 2.93V) and longer timeout - may delay µP startup in margin-critical 3.3V systems | Choose for TI ecosystem designs where 3.08V threshold better matches 3.3V rail tolerance; verify timing compatibility with µP reset hold requirement |
Compared with MAX6326UT29D+T and TPS3808G33DBVR, the ADPL62935SUK+T uniquely provides both RESET and RESET outputs in one SOT23-5 package - reducing component count and eliminating layout compromises in systems needing dual-polarity reset signaling.

FAQ
What is the exact reset threshold voltage for ADPL62935SUK+T?
The ADPL62935SUK+T has a factory-programmed reset threshold of 2.93V, with ±1.5% tolerance over the full -40°C to +125°C temperature range. This value is confirmed in the Threshold Suffix Guide (suffix 'S') and Electrical Characteristics table of the official Analog Devices datasheet Rev 1 (01/24). The ADPL62935SUK+T maintains this accuracy without external calibration.
Does ADPL62935SUK+T support both active-low and active-high reset outputs simultaneously?
Yes, the ADPL62935SUK+T provides two independent push-pull reset outputs: pin 1 (RESET) is active-low, and pin 3 (RESET) is active-high. Both assert synchronously when VCC drops below 2.93V or MR is pulled low, and both remain asserted for the full 140ms timeout period. This dual-output architecture eliminates the need for external inverters in systems requiring both polarities.
What is the minimum VCC voltage at which ADPL62935SUK+T guarantees correct reset output states?
The ADPL62935SUK+T guarantees valid RESET and RESET output states down to VCC = +1.0V, as explicitly stated in the General Description and Electrical Characteristics sections. This ensures deterministic reset behavior during deep brownout conditions - critical for preserving non-volatile memory writes and preventing undefined MCU states.
Can the manual reset input (MR) of ADPL62935SUK+T be left unconnected?
Yes, the MR pin of ADPL62935SUK+T features an internal 50kΩ pull-up resistor to VCC, so it may be left floating if manual reset functionality is not required. When unused, MR should either be left open or tied directly to VCC. No external pull-up is needed, and the device will operate normally with MR inactive.
What package type and RoHS status does ADPL62935SUK+T use?
The ADPL62935SUK+T uses a 5-pin SOT23-5 package (Analog Devices package code U5-1, outline 21-0057) and is RoHS-compliant. The '+' in the part number denotes lead-free and RoHS-compliant construction, and the 'T' suffix indicates tape-and-reel packaging for automated assembly. Land pattern number 91-0174 applies.
