Analog Devices Inc. ADM1816-10ARTZ-RL7

Overview

ADM1816-10ARTZ-RL7 from Analog Devices is a precision microprocessor reset circuit with open-drain output and internal 5.5 kΩ pull-up resistor, designed for monitoring 3.3 V and 3 V power supplies. It features a 2.88 V (typical) reset threshold, 150 ms reset timeout, −40°C to +105°C operating range, and 3-lead SOT-23 package-used in embedded controllers and industrial microprocessor systems requiring reliable power-on initialization.

For engineers reviewing the ADM1816-10ARTZ-RL7 datasheet, ADM1816-10ARTZ-RL7 pinout, ADM1816-10ARTZ-RL7 application, or ADM1816-10ARTZ-RL7 equivalent, this page delivers verified functional specifications, package mapping, real-world use scenarios, and validated alternative options for voltage supervisor selection in space-constrained, high-reliability designs.

Technical Context

The ADM1816-10ARTZ-RL7 implements a precision bandgap reference and comparator-based voltage detection architecture with built-in 150 ms power-up delay timer. Its open-drain RST output with integrated 5.5 kΩ pull-up eliminates external components while ensuring compatibility with standard logic-level reset inputs.

It operates across 1.2 V to 5.5 V supply range, draws only 4–10 µA quiescent current at 3.6 V, and guarantees reset assertion during VCC fall below 2.88 V (typical), with ±1.5% trip accuracy over temperature and line regulation.

FAQ

What is the exact reset threshold voltage of the ADM1816-10ARTZ-RL7?

The ADM1816-10ARTZ-RL7 has a nominal reset threshold of 2.88 V (typical), with guaranteed minimum and maximum values of 2.80 V and 2.97 V respectively across −40°C to +105°C. This value is factory-trimmed and specified in Table 1 of the Rev. F datasheet for the -10 variant.

Does the ADM1816-10ARTZ-RL7 require an external pull-up resistor on the RST pin?

No, the ADM1816-10ARTZ-RL7 includes an internal 5.5 kΩ pull-up resistor on the RST pin, as confirmed in Table 1 ("INTERNAL PULL-UP RESISTOR") and Figure 14 of the datasheet. This eliminates the need for external components and simplifies PCB layout.

Is the ADM1816-10ARTZ-RL7 pin-compatible with other ADM181x variants in SOT-23?

Yes, all ADM181x devices in the RT-3 (SOT-23) package-including ADM1816-10ARTZ-RL7-share identical 3-pin pinout (RST, VCC, GND) and mechanical footprint per Figures 2 and 15, enabling direct substitution within the same package family when electrical parameters align.

What is the reset timeout duration of the ADM1816-10ARTZ-RL7 during power-up?

The ADM1816-10ARTZ-RL7 guarantees a reset active time of 100–250 ms after VCC rises above the threshold, with 150 ms being the typical value. This is explicitly defined in Table 1 under "RESET ACTIVE TIME" and validated across temperature in Figure 6.

Can the ADM1816-10ARTZ-RL7 be used to monitor a 5 V supply?

No-the ADM1816-10ARTZ-RL7 is optimized for 3.3 V and 3 V supplies with its 2.88 V threshold. For 5 V monitoring, Analog Devices specifies the ADM1810–ADM1813 series (e.g., ADM1811-10ARTZ-RL7 with 4.35 V threshold); using ADM1816-10ARTZ-RL7 on 5 V would result in continuous reset assertion.
