Analog Devices Inc. ADM1810-10ARTZ-RL

Overview

ADM1810-10ARTZ-RL from Analog Devices is a precision active-low push-pull microprocessor reset circuit designed for 4.35 V supply monitoring in industrial and automotive systems. It delivers a guaranteed 150 ms reset timeout, operates across −40°C to +105°C, draws only 4–10 µA at 3.6 V, and is housed in a RoHS-compliant 3-lead SOT-23 package. It ensures safe system initialization after power-up in embedded controllers and intelligent instruments.

For engineers reviewing the ADM1810-10ARTZ-RL datasheet, ADM1810-10ARTZ-RL pinout, ADM1810-10ARTZ-RL application, or ADM1810-10ARTZ-RL equivalent, key selection criteria include its 4.35 V trip point tolerance (±0.10 V), push-pull output drive capability (350 µA source / 8 mA sink), and compatibility with microprocessor reset inputs without external components.

Technical Context

The ADM1810-10ARTZ-RL integrates a precision voltage reference, comparator, and 150 ms internal timing delay to generate a clean, glitch-free active-low reset signal upon power-up or brownout. Its trip point is factory-trimmed to 4.35 V (typical) with ±0.10 V min/max variation over temperature.

It uses an internal bandgap reference and temperature-compensated comparator to maintain stable threshold performance across −40°C to +105°C. The push-pull output eliminates need for external pull-up resistors and directly interfaces with standard CMOS/TTL reset inputs.

FAQ

What is the exact reset threshold voltage for ADM1810-10ARTZ-RL?

The ADM1810-10ARTZ-RL has a guaranteed reset threshold range of 4.25 V (min) to 4.49 V (max) at −40°C to +105°C, with 4.35 V typical. This specification is factory-trimmed and validated per Analog Devices' Rev. F datasheet Table 1, ensuring consistent 5 V supply monitoring without external calibration.

Does ADM1810-10ARTZ-RL require an external pull-up resistor on the RST pin?

No. ADM1810-10ARTZ-RL features an active-low push-pull output stage capable of sinking 8 mA and sourcing 350 µA, enabling direct connection to microprocessor reset inputs without any external components-including pull-up resistors-reducing BOM count and board area.

Can ADM1810-10ARTZ-RL be used with a 3.3 V supply?

No. ADM1810-10ARTZ-RL is specified for monitoring 5 V supplies with a 4.35 V threshold. For 3.3 V monitoring, Analog Devices recommends ADM1815-10ARTZ-RL (2.88 V threshold) or ADM1817-10ARTZ-RL (same threshold, active-high output). Using ADM1810-10ARTZ-RL on 3.3 V would cause continuous reset assertion.

What is the reset timeout behavior of ADM1810-10ARTZ-RL during power-up?

Upon VCC rising above the 4.35 V threshold, ADM1810-10ARTZ-RL holds RST low for 100–250 ms (typical 150 ms) before releasing it high. This delay ensures power supply stabilization and prevents premature microprocessor execution, as confirmed in Figure 10 and Table 1 of the Rev. F datasheet.

Is ADM1810-10ARTZ-RL RoHS compliant and lead-free?

Yes. The "Z" suffix in ADM1810-10ARTZ-RL explicitly denotes RoHS-compliant, lead-free construction per Analog Devices' Ordering Guide (Page 9, footnote 2). It meets JEDEC J-STD-020 moisture sensitivity level 1 and is qualified for reflow soldering per industry standards.
