Product details
Overview
DS1816-10 from Maxim Integrated (now Analog Devices) is a precision voltage-monitoring supervisory IC that provides active-low reset output for microprocessor systems. It features a 2.80–2.97 V VCC trip point (10% tolerance), 150 ms reset pulse width, open-drain RST output with internal 5 kΩ pull-up, and operates from -40°C to +85°C - used in embedded power sequencing and brownout protection for 3V systems.
For engineers reviewing the DS1816-10 datasheet, DS1816-10 pinout, DS1816-10 application, or DS1816-10 equivalent, key selection criteria include trip-point accuracy, reset timeout stability, open-drain drive capability, thermal range compliance, and TO-92/SOT-23 package compatibility with legacy board layouts.
Technical Context
The DS1816-10 implements a temperature-compensated bandgap reference and comparator to detect VCC deviations beyond its factory-trimmed 10% threshold (2.80–2.97 V). Its internal timing circuit ensures RST remains asserted for 100–250 ms after VCC returns to tolerance, independent of supply slew rate.
No external components are required for basic operation: the open-drain RST output includes an integrated 3.5–7.5 kΩ pull-up resistor, and the device draws only 28–35 µA quiescent current across its 0–5.5 V operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Trip Point | 2.80–2.97 V (10% tolerance at 25°C; enables reliable brownout detection for 3V systems) |
| Reset Pulse Width | 100–250 ms (guarantees processor stabilization before release; no external RC timing needed) |
| Output Type | Open-drain RST with internal 3.5–7.5 kΩ pull-up (simplifies interface to diverse logic families without external resistor) |
| Supply Range | 0–5.5 V (supports operation down to near-zero VCC for early-fail detection) |
| Quiescent Current | 28–35 µA (enables low-power always-on monitoring in battery-backed systems) |
| Operating Temp | -40°C to +85°C (validated for industrial-grade embedded control environments) |
Pinout & Package
DS1816-10 is available in TO-92 and SOT-23 packages. Both variants share identical pin mapping: Pin 1 = RST (active-low open-drain reset output), Pin 2 = VCC (power supply input), Pin 3 = GND (ground reference).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (RST) | Active-low reset output | Drives microprocessor /RESET pin low during power fault or startup; requires no external pull-up in most designs |
| 2 (VCC) | Power supply input | Monitored rail; trip point defined relative to this pin; supports 0–5.5 V operation |
| 3 (GND) | Ground reference | Return path for internal reference and comparator; must be low-impedance for accurate threshold tracking |
Key Features
| Feature | Design Value |
|---|---|
| Precision voltage monitoring | Factory-trimmed 10% VCC threshold (2.80–2.97 V) with temperature compensation ensures stable trip point across -40°C to +85°C |
| Guaranteed reset timeout | 100–250 ms minimum active-reset duration prevents premature processor release during supply recovery |
| Integrated pull-up resistor | Internal 3.5–7.5 kΩ pull-up eliminates need for external component while maintaining compatible VOH levels |
| Low-power supervision | 28–35 µA ICC enables continuous monitoring in energy-constrained applications without compromising battery life |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage-monitoring reset applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809TRD1+T | VCC trip = 3.08 V (±2.5%), fixed 140 ms reset timeout, same SOT-23-3 package | Higher trip point; tighter tolerance but less margin for 3V system drift | Select when precise 3.08 V threshold and shorter reset hold time are required |
| TPS3808G12DBVR | VCC trip = 1.22 V (adjustable via external divider), 200 ms timeout, higher ICC (1.5 µA typical) | Requires external resistors; supports custom thresholds but adds BOM complexity | Select when system needs programmable trip point or multi-rail monitoring capability |
Compared with MAX809TRD1+T and TPS3808G12DBVR, the DS1816-10 offers optimized 10% tolerance for 3V rails, integrated pull-up, and minimal external component count - making it ideal for cost-sensitive, space-constrained industrial controls where fixed 2.80–2.97 V detection suffices.

FAQ
What is the exact VCC trip point range for DS1816-10?
The DS1816-10 has a guaranteed VCC trip point range of 2.80 V to 2.97 V at 25°C, representing a 10% tolerance centered on 2.88 V. This range is temperature-compensated and validated across -40°C to +85°C per the official DS1816 datasheet. The DS1816-10 uses factory trimming to achieve this specification without external calibration.
Does DS1816-10 require an external pull-up resistor on the RST pin?
No, the DS1816-10 integrates a 3.5–7.5 kΩ internal pull-up resistor on the open-drain RST output, eliminating the need for an external component in standard 3.3 V or 5 V logic interfaces. An external 1 kΩ pull-up may be added only if faster rise time or higher drive strength is required - as noted in DS1816 datasheet Note 3. The DS1816-10 functions correctly without it.
Can DS1816-10 be used with a 3.3 V microcontroller?
Yes, the DS1816-10 is explicitly designed for 3V systems: its 2.80–2.97 V trip point provides appropriate hysteresis margin below nominal 3.3 V supply, and its RST output is compatible with standard CMOS/TTL inputs. The DS1816-10 meets all timing and voltage interface requirements for common 3.3 V microcontrollers including ARM Cortex-M and PIC families.
What is the reset timeout duration of DS1816-10 after VCC recovery?
The DS1816-10 holds RST active for 100–250 ms after VCC returns to within tolerance, with a typical value of 150 ms. This delay is internally generated and independent of external components or supply slew rate, ensuring consistent processor stabilization across operating conditions. The DS1816-10 guarantees minimum 100 ms hold time even at temperature extremes.
Which packages are available for DS1816-10?
The DS1816-10 is offered in both TO-92 and SOT-23 packages, with identical pinout (RST-VCC-GND) and electrical specifications. Mechanical drawings for both variants are published in the Maxim Integrated (Analog Devices) DS1816 datasheet. The DS1816-10 allows direct PCB layout reuse between through-hole and surface-mount versions where footprint conversion is supported.
