Product details
Overview
HA1631D01MMEL-E from Renesas is a dual CMOS comparator with push-pull full-swing outputs, designed for low-voltage single-supply operation (1.8–5.5 V), 5 µA typical supply current per comparator, 5 mV maximum input offset voltage, and rail-to-rail input common-mode range including ground. It enables direct interfacing with TTL/CMOS logic in battery-powered sensor monitoring and portable power management circuits.
For engineers reviewing the HA1631D01MMEL-E datasheet, HA1631D01MMEL-E pinout, HA1631D01MMEL-E application, or HA1631D01MMEL-E equivalent, key selection criteria include ultra-low IDD at 1.8 V, guaranteed VOHmin = 2.9 V at VDD = 3.0 V, push-pull output drive capability (13 mA source / 14 mA sink), and compatibility with MMPAK-8 package constraints in space-constrained PCB layouts.
Technical Context
The HA1631D01MMEL-E integrates two independent high-precision comparators on a single die, each featuring picoamp-level input bias current (1 pA typ) and 80 dB typical CMRR, enabling accurate threshold detection in high-impedance signal paths. Its push-pull output stage eliminates external pull-up resistors and supports full-swing logic-level transitions across the entire 1.8–5.5 V supply range.
Designed for single-supply systems, the device accepts input voltages down to VSS (0 V) and up to VDD, with internal ESD protection and guaranteed operation from –40°C to +85°C. Propagation delay is 1.20 µs (TPLH) and 0.55 µs (TPHL) at 100 mV overdrive and CL = 15 pF, supporting moderate-speed window-compare and zero-crossing detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V - Enables operation from single-cell Li-ion (3.0 V), coin cell (3 V), or 5 V logic rails without level-shifting. |
| Supply Current (per comparator) | 5 µA typ at 25°C - Supports multi-year battery life in always-on sensor wake-up circuits. |
| 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 typ - Minimizes loading error on high-Z sources like photodiodes or piezoelectric sensors. |
| Output Drive Capability | 13 mA source / 14 mA sink - Directly drives LED indicators, small relays, or standard CMOS/TTL inputs without buffer stages. |

MMPAK-8 package: 2.8 mm × 2.95 mm × 0.6 mm body, 0.65 mm pitch, Pb-free lead frame, 8-pin surface-mount with exposed thermal pad (PLSP0008JC-A).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground reference for both comparators and output stage; must be low-impedance connection to minimize noise coupling. |
| 2 | VIN1(+) | Inverting input of Comparator 1 - Used for reference voltage connection in non-inverting configurations. |
| 3 | VIN1(–) | Non-inverting input of Comparator 1 - Accepts sensed signal; supports rail-to-rail common-mode range. |
| 4 | VOUT1 | Push-pull output of Comparator 1 - Provides full-swing digital output (0 V to VDD) compatible with downstream logic. |
| 5 | VIN2(+) | Inverting input of Comparator 2 - Independent channel for dual-threshold or window-compare applications. |
| 6 | VIN2(–) | Non-inverting input of Comparator 2 - Electrically isolated from Channel 1; same input specifications apply. |
| 7 | VOUT2 | Push-pull output of Comparator 2 - Fully independent output; no cross-talk between channels (tested per Fig. 1-25). |
| 8 | VDD | Positive supply rail - Powers both comparators and output drivers; bypass capacitor (0.1 µF) required near pin. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM393DR | Higher supply current (500 µA typ), open-drain output only, no rail-to-rail input (VCM = 0 to VDD–1.5 V). | Requires external pull-up; unsuitable for ground-referenced sensing or ultra-low-power designs. | Select when cost is primary constraint and 5 µA quiescent current is not required. |
| TLV3702IDR | Lower VIO (1.5 mV max), rail-to-rail input/output, but higher IDD (35 µA typ) and 5 V absolute max supply. | Superior precision but incompatible with 5.5 V systems; lacks guaranteed 1.8 V operation. | Select when sub-mV offset is critical and supply is strictly ≤5.0 V with moderate power budget. |
Compared with LM393DR and TLV3702IDR, the HA1631D01MMEL-E uniquely combines 1.8 V operation, 5 µA supply current, rail-to-rail input including ground, and push-pull output - making it optimal for space- and energy-constrained battery-powered systems requiring direct logic interfacing.

FAQ
What is the minimum operating voltage for HA1631D01MMEL-E?
The HA1631D01MMEL-E operates down to 1.8 V, enabling use with single-cell lithium batteries (nominal 3.0 V) and low-voltage microcontrollers. At 1.8 V, it maintains full functionality including rail-to-rail input range and 5 µA typical supply current - verified per Electrical Characteristics table on page 3 of the datasheet.
Does HA1631D01MMEL-E support ground-referenced input signals?
Yes. The HA1631D01MMEL-E features an input common-mode voltage range that includes VSS (0 V), allowing direct connection of signals referenced to ground - such as those from current-sense amplifiers or resistive sensors - without level-shifting circuitry.
What is the output configuration of HA1631D01MMEL-E?
The HA1631D01MMEL-E has push-pull (totem-pole) outputs on both channels. This means each output can actively drive high (to VDD) or low (to VSS), eliminating the need for external pull-up resistors and enabling direct interface with standard CMOS/TTL logic inputs.
Can HA1631D01MMEL-E replace HA1631D02MMEL-E in a design?
No - HA1631D01MMEL-E and HA1631D02MMEL-E differ in supply current: HA1631D01MMEL-E draws 5 µA typ per comparator, while HA1631D02MMEL-E draws 100 µA typ. Swapping them may cause unexpected current draw or timing changes; verify IDD requirements before substitution.
Is HA1631D01MMEL-E available in RoHS-compliant packaging?
Yes. The HA1631D01MMEL-E uses a Pb-free lead frame in the MMPAK-8 package (PLSP0008JC-A), fully compliant with RoHS Directive 2011/65/EU and JEDEC standards, as confirmed in the Package Dimensions section (page 26) and Ordering Information table (page 2).
