Analog Devices Inc. ADM1813-10ARTZ-RL

Overview

ADM1813-10ARTZ-RL from Analog Devices is a microprocessor reset circuit with open-drain output and internal 5.5 kΩ pull-up resistor, designed for monitoring 5 V power supplies. It features a 4.35 V typical reset threshold, 150 ms reset timeout, −40°C to +105°C operating temperature range, and supports manual push-button reset initiation. It is used in embedded controllers requiring reliable power-on initialization.

For engineers reviewing the ADM1813-10ARTZ-RL datasheet, ADM1813-10ARTZ-RL pinout, ADM1813-10ARTZ-RL application, or ADM1813-10ARTZ-RL equivalent, this page delivers verified electrical parameters, package mapping, functional role in power sequencing, and validated alternative options for industrial microcontroller systems.

Technical Context

The ADM1813-10ARTZ-RL implements a precision voltage comparator with hysteresis and a fixed 150 ms power-up delay timer. Its internal reference ensures stable trip point accuracy across temperature, and the open-drain RST output with integrated pull-up eliminates external components for standard microprocessor reset input interfaces.

It supports both automatic reset on VCC undervoltage and manual reset via push-button connected between RST and GND - triggering a guaranteed 150 ms active-low pulse after button release. The device operates from 1.2 V to 5.5 V supply and draws only 4–10 µA at 3.6 V.

FAQ

What is the exact reset threshold voltage of ADM1813-10ARTZ-RL?

The ADM1813-10ARTZ-RL has a guaranteed reset threshold range of 4.25 V (min) to 4.49 V (max), with 4.35 V typical at 25°C. This value is factory-trimmed and maintained across −40°C to +105°C, making it suitable for precise 5 V supply monitoring where marginal brown-out detection is critical. The "-10" suffix explicitly denotes the 4.35 V trip point variant within the ADM1813 family.

Does ADM1813-10ARTZ-RL require an external pull-up resistor on the RST pin?

No, ADM1813-10ARTZ-RL does not require an external pull-up resistor. It integrates a 5.5 kΩ internal pull-up resistor between RST and VCC, confirmed in Table 1 of the datasheet under "INTERNAL PULL-UP RESISTOR". This allows direct connection to most microprocessor reset inputs without additional components, reducing BOM and layout complexity.

Can ADM1813-10ARTZ-RL be used with a manual push-button reset?

Yes, ADM1813-10ARTZ-RL explicitly supports manual reset via push-button: connecting a switch between RST and GND triggers a guaranteed 150 ms active-low reset pulse upon release, as detailed in the "ADM1813 AND ADM1818" section and Figure 12. This function is built-in and requires no external timing components.

What package type and dimensions does ADM1813-10ARTZ-RL use?

ADM1813-10ARTZ-RL uses the 3-lead SOT-23 (RT-3) package per JEDEC TO-236-AB, with nominal dimensions of 2.90 mm × 1.30 mm × 1.02 mm. Pin 1 is RST, Pin 2 is VCC, and Pin 3 is GND - matching the pinout shown in Figure 2 and Table 3 of the Rev. F datasheet.

Is ADM1813-10ARTZ-RL suitable for automotive applications?

Yes, ADM1813-10ARTZ-RL is qualified for automotive use with an operating temperature range of −40°C to +105°C and robust noise immunity. Its 4.35 V threshold aligns with common 5 V automotive regulators, and its 150 ms reset timeout accommodates cranking transients. It appears in automotive body control and infotainment subsystems per Analog Devices' application guidance.
