Product details
Overview
DS1233Z-10/T&R from Analog Devices is a precision 5V microprocessor supervisory circuit in SOT-223 package, providing power-on reset, power-fail detection at 4.25V–4.49V trip point (10% tolerance), 350ms reset pulse duration, internal 5kΩ pull-up, and pushbutton debouncing. It ensures reliable system initialization in embedded controllers and industrial microprocessor systems.
For engineers reviewing the DS1233Z-10/T&R datasheet, DS1233Z-10/T&R pinout, DS1233Z-10/T&R application, or DS1233Z-10/T&R equivalent, key selection criteria include VCC trip accuracy (±125mV), guaranteed 350ms reset hold time after power recovery or button release, SOT-223 thermal performance, and compatibility with 5V logic-level reset interfaces.
Technical Context
The DS1233Z-10/T&R integrates a temperature-compensated voltage reference and comparator to monitor VCC against a fixed 10% threshold (4.25V–4.49V). It asserts an active-low RESET signal during out-of-tolerance conditions and holds it for 350ms after VCC returns to spec or after pushbutton release.
Its dual-function architecture supports both autonomous power monitoring and external pushbutton control: RST pin serves as both output and input-detecting falling edges for button press initiation and rising edges for release-triggered reset generation-with internal debouncing and timing control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Trip Point | 4.25V to 4.49V (10% tolerance); ensures reset activation before 5V supply drops below safe microprocessor operating margin |
| Reset Pulse Duration | 250–450ms (typ. 350ms); guarantees sufficient stabilization time for CPU and peripherals post-power recovery or button release |
| Operating Temperature | -40°C to +85°C; validated for industrial-grade embedded applications without derating |
| Supply Voltage Range | 1.2V to 5.5V; supports operation across brown-out and battery-backed scenarios |

| Output Sink Current | 8mA @ 0.4V VOL; drives standard TTL/CMOS reset inputs without buffer stage |
Pinout & Package
SOT-223 package (4-pin, surface-mount), thermally enhanced for industrial ambient operation; pin 4 is dedicated ground for improved noise immunity and thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | VCC | Primary power supply input; monitored for 10% under-voltage condition triggering reset assertion |
| Pin 2 | RESET | Open-drain active-low reset output; also accepts external pushbutton signal for manual reset initiation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809TRD2+T | Fixed 3.08V reset threshold; no pushbutton support; SOT-23-3 package | Single-function power monitor only; unsuitable where manual reset is required | Select when only basic 3.3V supply supervision needed and board space is constrained |
| TPS3808G12DBVR | Adjustable reset threshold via external resistor divider; 200ms min reset timeout; SOT-23-6 | Requires external components for threshold setting; lacks integrated pushbutton debounce | Choose for designs needing custom trip points or tighter reset timing control, accepting added BOM complexity |
Compared with MAX809TRD2+T and TPS3808G12DBVR, the DS1233Z-10/T&R uniquely combines 10%-tolerance 5V monitoring, pushbutton debouncing, and 350ms reset hold in a single SOT-223 package-reducing component count and eliminating firmware-level reset management in cost-sensitive industrial controllers.

FAQ
What is the exact VCC trip point range for DS1233Z-10/T&R?
The DS1233Z-10/T&R has a guaranteed VCC trip point range of 4.25V to 4.49V, corresponding to its 10% tolerance specification for nominal 5V supply monitoring. This range is validated across the full -40°C to +85°C operating temperature and ensures reset assertion before microprocessor operational limits are exceeded. The DS1233Z-10/T&R uses a precision temperature-compensated reference to maintain this accuracy without external calibration.
Does DS1233Z-10/T&R support manual reset via pushbutton?
Yes, the DS1233Z-10/T&R supports manual reset through its RESET pin, which functions bidirectionally: it outputs an active-low reset signal and also detects falling edges from an external pushbutton. Upon button release, the DS1233Z-10/T&R debounces the signal and asserts a precise 350ms reset pulse. A 100pF–0.01μF capacitor between RST and ground is required for proper operation of the DS1233Z-10/T&R in pushbutton mode.
What package type and pin count does DS1233Z-10/T&R use?
The DS1233Z-10/T&R uses a 4-pin SOT-223 surface-mount package with pins assigned as VCC (1), RESET (2), GND (3), and GND (4). Pin 4 provides a dedicated ground connection to improve thermal dissipation and reduce ground noise coupling-distinct from the 3-pin TO-92 variant. This SOT-223 configuration is supplied in tape-and-reel format per the "/T&R" suffix in DS1233Z-10/T&R.
How long is the reset pulse duration of DS1233Z-10/T&R?
The DS1233Z-10/T&R guarantees a reset pulse duration of 250ms to 450ms, with a typical value of 350ms. This timing applies both after VCC returns to in-tolerance conditions and after pushbutton release. The DS1233Z-10/T&R implements this using an internal timer that is independent of supply voltage fluctuations, ensuring consistent reset hold time across operating conditions.
Is DS1233Z-10/T&R RoHS-compliant and lead-free?
Yes, the DS1233Z-10/T&R is RoHS-compliant and lead-free, indicated by the "+" suffix in its full ordering code (DS1233Z-10+/T&R). Analog Devices confirms compliance with EU RoHS Directive 2011/65/EU and related amendments. The SOT-223 package uses matte tin lead finish, and the DS1233Z-10/T&R meets JEDEC J-STD-020 moisture sensitivity level 3 requirements for surface-mount assembly.
