Product details

Overview

HA1631D04MMEL-E from Renesas is a dual CMOS comparator with open-drain output, designed for low-voltage, ultra-low-power applications. It operates from 1.8 V to 5.5 V, draws only 100 µA typical supply current per comparator, features 5 mV max input offset voltage and 1 pA typical input bias current, and supports level-shifting via external pull-up resistors - ideal for battery-powered sensor interface and portable voltage monitoring circuits.

For engineers reviewing the HA1631D04MMEL-E datasheet, HA1631D04MMEL-E pinout, HA1631D04MMEL-E application, or HA1631D04MMEL-E equivalent, this page delivers verified electrical specs, package mapping to MMPAK-8, confirmed open-drain behavior, real-world timing performance (TPHL = 0.17 µs, tf = 7 ns at VDD = 3 V), and direct alternative part guidance for design-in continuity.

Technical Context

The HA1631D04MMEL-E implements two independent high-impedance comparators in a single die, each with rail-to-rail input common-mode range including ground and open-drain outputs enabling flexible logic-level translation. Its architecture eliminates internal output pull-ups, requiring external resistors to define high-state voltage and sink current capability.

It is optimized for single-supply operation across wide temperature (–40°C to +85°C) and supply voltage (1.8–5.5 V) ranges, with PSRR of 60–80 dB and CMRR of 50–70 dB - ensuring stable decision thresholds in noisy mixed-signal environments such as power management subsystems and analog front-ends.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	1.8 V to 5.5 V - enables direct integration with Li-ion, coin-cell, and 3.3 V/5 V logic systems without level shifters.
Supply Current (per comparator)	100 µA typical at VDD = 3 V - supports multi-year battery life in always-on sensing nodes.
Input Offset Voltage	≤5 mV max - ensures reliable detection of small differential signals (e.g., thermistor or current-sense amplifier outputs).
Input Bias Current	1 pA typical - preserves signal integrity in high-impedance sensor interfaces (e.g., pH electrodes, photodiodes).
Output Configuration	Open-drain - allows wired-OR logic, I²C-compatible bus sharing, and programmable output voltage via external pull-up.
Propagation Delay	TPHL = 0.17 µs, TPLH not specified for open-drain - defines minimum response time for fast threshold detection with external load.
Operating Temperature	–40°C to +85°C - qualified for industrial and automotive cabin ambient conditions.

Pinout & Package

MMPAK-8 package (Renesas code PLSP0008JC-A), 2.8 mm × 2.95 mm footprint, 0.65 mm pitch, Pb-free lead frame, 8-pin surface-mount with exposed pad for thermal enhancement.

Pin/Terminal	Circuit Role	Design Meaning
VDD	Positive supply rail	Single power input for both comparators; must be decoupled locally to suppress supply noise coupling into inputs.
VSS	Ground reference	Common return path for inputs, outputs, and supply; requires low-impedance connection to minimize offset drift.
VIN1(+), VIN1(–)	Channel 1 differential inputs	High-impedance inputs supporting common-mode range from –0.1 V to VDD – 0.1 V; no internal hysteresis.
VIN2(+), VIN2(–)	Channel 2 differential inputs	Independent of Channel 1; identical electrical characteristics and layout sensitivity.
VOUT1	Open-drain output for Channel 1	Active-low only; requires external pull-up resistor to define logic-high voltage and sink current limit (max 28 mA).
VOUT2	Open-drain output for Channel 2	Electrically isolated from VOUT1; supports independent pull-up networks for dual-threshold or priority logic.

Key Features

Feature	Design Value
Ultra-low supply current	100 µA per comparator at 3 V - reduces quiescent power in always-on monitoring without sacrificing speed.
Open-drain output architecture	Enables bidirectional level shifting and wired-AND functionality - critical for shared interrupt buses and multi-source signaling.
Rail-to-rail input common-mode range	Includes ground (–0.1 V min) and extends to VDD – 0.1 V - simplifies interfacing with sensors and DACs operating near supply rails.
On-chip ESD protection	HBM ≥2 kV - provides robustness against handling and board-level transients without external protection diodes.
Pb-free MMPAK-8 package	0.65 mm pitch, 2.8 × 2.95 mm body - supports high-density PCB layouts and automated optical inspection (AOI) compatibility.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual open-drain comparator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
LM393DR	Higher supply current (500 µA typ), wider VDD range (2–36 V), no rail-to-rail inputs, push-pull output (requires external pull-up for open-drain emulation).	Less suitable for <1.8 V or ultra-low-power designs; better for industrial 12–24 V systems with higher noise immunity needs.	Select LM393DR only if higher supply voltage tolerance or legacy footprint compatibility is required; redesign needed for true open-drain behavior.
TLV3702IDR	Lower input offset (1.5 mV max), rail-to-rail inputs/outputs, 85 µA supply current, but push-pull output - lacks native open-drain flexibility.	Superior precision and speed, but requires external MOSFET or logic gate to emulate open-drain OR function.	Choose TLV3702IDR when offset voltage or propagation delay is critical; accept added complexity for open-drain emulation.

Compared with LM393DR and TLV3702IDR, HA1631D04MMEL-E uniquely combines true open-drain outputs, 1.8 V operation, and 100 µA supply current - making it optimal for space-constrained, battery-sensitive designs where level-shifting and low quiescent power are non-negotiable.

FAQ

What is the maximum sink current capability of HA1631D04MMEL-E?

The HA1631D04MMEL-E supports up to 28 mA maximum continuous output sink current per channel, as specified in Absolute Maximum Ratings. This value is validated under thermal limits and applies to both VOUT1 and VOUT2 independently. Designers must ensure external pull-up resistor values and PCB copper area maintain junction temperature within –40°C to +85°C operating range when sinking near-maximum current.

Does HA1631D04MMEL-E include internal hysteresis?

No, HA1631D04MMEL-E does not include internal hysteresis. The device relies on external positive feedback (e.g., resistor network from output to non-inverting input) to implement user-defined hysteresis. This design choice preserves input impedance integrity and allows precise tailoring of threshold windows for noise-prone environments like motor control feedback paths.

Can HA1631D04MMEL-E operate from a 1.8 V supply while driving a 3.3 V logic interface?

Yes - HA1631D04MMEL-E's open-drain outputs enable level shifting: connect the external pull-up resistor to 3.3 V, and the comparator will sink current when active, pulling the node to near 0 V. When inactive, the output floats to 3.3 V, satisfying standard CMOS logic high requirements without additional level translators.

What is the input common-mode voltage range for HA1631D04MMEL-E at 1.8 V supply?

At VDD = 1.8 V, the input common-mode voltage range is specified as –0.1 V to 1.7 V (VDD – 0.1 V), per Electrical Characteristics table. This rail-to-rail capability allows direct interfacing with sensors or DACs whose outputs swing from ground to supply - critical for accurate low-voltage threshold detection in wearables and hearing aids.

Is HA1631D04MMEL-E pin-compatible with other variants in the HA1631Dxx family?

Yes - all HA1631Dxx variants (D01 through D04) share identical MMPAK-8 and TSSOP-8 pinouts. HA1631D04MMEL-E is functionally interchangeable with HA1631D03MM in the same package; differences lie solely in supply current (100 µA vs. 5 µA) and output stage (both open-drain), not pin assignment or footprint.
