Analog Devices Inc. ADM1816-10AKSZ-RL

Overview

ADM1816-10AKSZ-RL from Analog Devices is a precision 3-pin open-drain microprocessor reset circuit with internal pull-up resistor, designed to monitor 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 SC70 package for space-constrained embedded systems requiring reliable power-on initialization.

For engineers reviewing the ADM1816-10AKSZ-RL datasheet, ADM1816-10AKSZ-RL pinout, ADM1816-10AKSZ-RL application, or ADM1816-10AKSZ-RL equivalent, this device serves as a low-power, temperature-stable voltage supervisor for industrial controllers, automotive ECUs, and intelligent instrumentation where supply rail integrity must be verified before system boot.

Technical Context

The ADM1816-10AKSZ-RL implements a bandgap-based voltage reference with comparator hysteresis and a fixed 150 ms power-up delay timer. Its open-drain output with integrated 3.5–7.5 kΩ pull-up enables direct interface to microcontroller reset inputs without external components.

It operates across full industrial temperature range (−40°C to +105°C), supports supply voltages from 1.2 V to 5.5 V, and delivers guaranteed reset assertion during VCC fall below 2.88 V (typ) with 10 µs response time - ensuring deterministic behavior under brownout and startup transients.

FAQ

What is the exact reset threshold voltage of the ADM1816-10AKSZ-RL?

The ADM1816-10AKSZ-RL has a nominal reset threshold of 2.88 V (typical), with min/max 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, targeting reliable supervision of 3.3 V and 3 V supply rails.

Does the ADM1816-10AKSZ-RL require an external pull-up resistor?

No - the ADM1816-10AKSZ-RL integrates an internal pull-up resistor (3.5–7.5 kΩ) on its open-drain RST output, eliminating the need for external components. This feature is explicitly confirmed in Table 1 ("INTERNAL PULL-UP RESISTOR") and Functional Block Diagram Figure 1 for ADM1811/ADM1816 variants.

What package type is used for the ADM1816-10AKSZ-RL?

The ADM1816-10AKSZ-RL uses the SC70-3 (KS-3) package - a 3-lead, gull-wing surface-mount outline measuring 2.0 mm × 1.25 mm. This is confirmed in the Ordering Guide (Page 9) and Outline Dimensions (Figure 16, Page 8) of the Rev. F datasheet.

Can the ADM1816-10AKSZ-RL be used with a manual reset button?

No - only ADM1813 and ADM1818 variants include push-button reset functionality. The ADM1816-10AKSZ-RL is a dedicated voltage supervisor without manual reset capability, as stated in the "ADM1811 AND ADM1816" section (Page 7) and confirmed by absence of push-button timing diagrams in its functional description.

What is the reset timeout duration of the ADM1816-10AKSZ-RL?

The ADM1816-10AKSZ-RL provides a fixed 150 ms (typical) reset timeout after VCC rises above the threshold, with guaranteed range of 100–250 ms. This delay is implemented internally and does not require external components, as documented in Table 1 ("RESET ACTIVE TIME") and Theory of Operation (Page 7).
