Analog Devices Inc. ADM1816-R23ARTZ-RL

Overview

ADM1816-R23ARTZ-RL from Analog Devices is a precision microprocessor reset circuit with active-low open-drain output and internal 5.5 kΩ pull-up resistor, designed to monitor 2.5 V supply rails. It features a 2.31 V typical reset threshold, 150 ms reset timeout, −40°C to +105°C operating range, and SC70-3 package. Used in embedded controllers for safe power-on initialization.

For engineers reviewing the ADM1816-R23ARTZ-RL datasheet, ADM1816-R23ARTZ-RL pinout, ADM1816-R23ARTZ-RL application, or ADM1816-R23ARTZ-RL equivalent, this page delivers verified specifications, real-world use cases, pin-level design meaning, and validated alternative options for industrial-grade voltage monitoring.

Technical Context

The ADM1816-R23ARTZ-RL implements a bandgap-based voltage reference with comparator hysteresis and a fixed 150 ms power-up delay timer. Its open-drain RST output with integrated pull-up eliminates external components when interfacing with standard CMOS reset inputs.

It operates across 1.2 V to 5.5 V supply range while consuming only 4–10 µA at 3.6 V, enabling use in low-power systems. The device asserts reset when VCC falls below 2.31 V (typ) and holds reset active for ≥100 ms after VCC rises above threshold.

FAQ

What is the exact reset threshold voltage for ADM1816-R23ARTZ-RL?

The ADM1816-R23ARTZ-RL has a guaranteed reset threshold range of 2.25 V (minimum) to 2.37 V (maximum), with 2.31 V typical at 25°C. This value is specified in Table 1 of the Rev. F datasheet and applies across the full −40°C to +105°C operating temperature range, ensuring consistent 2.5 V rail monitoring performance in industrial environments.

Does ADM1816-R23ARTZ-RL require an external pull-up resistor?

No, ADM1816-R23ARTZ-RL includes an internal 5.5 kΩ pull-up resistor on its open-drain RST output, as confirmed in Table 1 (Internal Pull-Up Resistor section) and Figure 14 of the datasheet. This eliminates the need for external components when interfacing with standard CMOS reset inputs, simplifying layout and reducing BOM cost.

What package type and dimensions does ADM1816-R23ARTZ-RL use?

ADM1816-R23ARTZ-RL uses the SC70-3 (KS-3) package: 2.00 mm × 1.25 mm body size, 0.65 mm lead pitch, and 0.95 mm maximum height. These mechanical dimensions are documented in Figure 16 and the Outline Dimensions section (Page 8) of the Rev. F datasheet, and are JEDEC SC70-compliant.

Can ADM1816-R23ARTZ-RL be used with a manual reset button?

No - ADM1816-R23ARTZ-RL lacks push-button reset functionality. Only ADM1813 and ADM1818 variants support manual reset via RST-to-GND switch, as explicitly stated in the "ADM1813 AND ADM1818" section (Page 7) and functional block diagrams. ADM1816-R23ARTZ-RL is a dedicated voltage monitor without button-detection circuitry.

What is the reset timeout duration for ADM1816-R23ARTZ-RL?

The ADM1816-R23ARTZ-RL provides a guaranteed reset active time of 100 ms minimum to 250 ms maximum after VCC rises above the threshold, with 150 ms typical. This timing is defined in the "RESET ACTIVE TIME" row of Table 1 and ensures safe microprocessor initialization across temperature and voltage variations.
