Product details

Overview

DS1817-10+ from Maxim Integrated (now Analog Devices) is a precision voltage-monitoring supervisory IC that provides active-high reset signaling for microprocessors during power failure or brownout events. It features a 10% V_CC trip point (2.80–2.97 V), 150 ms reset pulse width, push-pull output, and operates from -40°C to +85°C in SOT-23 or TO-92 packages - used in embedded systems requiring reliable power-up sequencing and supply monitoring.

For engineers reviewing the DS1817-10+ datasheet, DS1817-10+ pinout, DS1817-10+ application, or DS1817-10+ equivalent, key selection criteria include its fixed 10% tolerance threshold, guaranteed 150 ms reset hold time after V_CC recovery, push-pull output drive capability (350 µA high, 10 mA low), low 28–35 µA operating current, and compatibility with 3.0 V systems.

Technical Context

The DS1817-10+ integrates a temperature-compensated bandgap reference and comparator to detect when V_CC falls below its factory-trimmed 10% threshold (2.80–2.97 V). Its internal timing circuit ensures RST remains asserted for 100–250 ms after V_CC returns to tolerance, with typical 150 ms duration.

No external components are required: the device combines voltage sensing, hysteresis, and reset timing in a single chip. The push-pull output eliminates need for an external pull-up resistor and supports direct interface to CMOS inputs across 1.2–5.5 V supply range.

Reset Pulse Width	100–250 ms (guaranteed minimum 100 ms; typical 150 ms hold after V_CC recovery)
Output Type	Push-pull active-high (no external pull-up required; VOH = V_CC − 0.1 V @ 0–500 µA)
Supply Current	28–35 µA (enables ultra-low-power system monitoring)

Equivalent & Alternatives

The following parts are listed as comparable options for similar voltage-monitoring reset applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MAX6326–30D2T+	3.0 V ±2% threshold (tighter tolerance); 200 ms reset timeout; open-drain output	Requires external pull-up; better suited for systems needing precise 3.0 V trip with longer reset hold	Select if 2% accuracy and 200 ms hold outweigh need for push-pull simplicity
TPS3808G30DBVR	3.0 V ±0.5% threshold; adjustable delay option; 1.8–6.0 V supply range; push-pull output	Higher cost; requires external capacitor for delay tuning; broader voltage support	Choose when sub-1% threshold accuracy and flexible timing configuration are critical

Compared with MAX6326–30D2T+ and TPS3808G30DBVR, the DS1817-10+ offers lower system cost and simpler layout due to its integrated push-pull output and zero-external-component design, while delivering sufficient accuracy (±10%) and timing (150 ms typical) for cost-sensitive 3.0 V industrial and IoT applications.

FAQ

What is the exact V_CC trip point range for DS1817-10+?

The DS1817-10+ has a factory-trimmed V_CC trip point of 2.80 V (min) to 2.97 V (max), corresponding to a nominal 3.0 V supply with ±10% tolerance. This range is specified over the full operating temperature range (-40°C to +85°C) and is enabled by an internal temperature-compensated voltage reference. The DS1817-10+ does not require external calibration or trimming to achieve this accuracy.

Does DS1817-10+ require an external pull-up resistor on the RST pin?

No, the DS1817-10+ features a push-pull output stage on the RST pin, eliminating the need for an external pull-up resistor. It actively drives high (VOH = V_CC − 0.1 V) and low (VOL < 0.4 V at 10 mA sink) to interface directly with standard CMOS inputs. This simplifies PCB layout and reduces BOM count compared to open-drain reset supervisors like the MAX6326–30D2T+.

How long does the DS1817-10+ hold the RST signal active after V_CC recovers?

The DS1817-10+ holds RST active for 100–250 ms after V_CC rises above its trip threshold, with a typical value of 150 ms. This guaranteed minimum timeout ensures microprocessor and power supply stabilization before release. The timing is internally generated and independent of external components, making the DS1817-10+ robust against capacitor aging or temperature drift seen in RC-based solutions.

Can DS1817-10+ operate from a 1.8 V supply?

No, the DS1817-10+ is not rated for 1.8 V operation. Its absolute maximum V_CC rating is 5.5 V, but its functional operation requires V_CC ≥ 2.80 V to ensure proper comparator and reference behavior. The device is optimized for 3.0 V systems (trip point 2.80–2.97 V); for 1.8 V applications, consider alternatives such as the TPS3808G18 or MAX6371.

Is DS1817-10+ available in both TO-92 and SOT-23 packages?

Yes, the DS1817-10+ is offered in both TO-92 (through-hole) and SOT-23 (surface-mount) packages. Both variants share identical electrical specifications, pinout (RST-V_CC-GND), and thermal performance. The SOT-23 version is marked "DS1817-10+" on top; the TO-92 version uses same marking and shares identical functionality - allowing seamless migration between assembly processes without redesign.
