Product details
Overview
HA17393F-EL-E from Renesas Electronics (formerly Hitachi) is a dual general-purpose comparator IC designed for power control systems and industrial signal conditioning. It operates from a single 2–36 V supply, draws only 0.8 mA typical supply current, features ±2 mV input offset voltage, and supports common-mode input down to ground-enabling direct sensing of low-side current or battery voltage in DC-DC converters.
For engineers reviewing the HA17393F-EL-E datasheet, HA17393F-EL-E pinout, HA17393F-EL-E application, or HA17393F-EL-E equivalent, key selection criteria include its rail-to-rail input capability at single supply, 1.3 µs response time, CMOS-compatible open-collector output, and FP-8D package suitability for space-constrained industrial PCBs.
Technical Context
The HA17393F-EL-E integrates two independent comparators with bipolar input stages enabling wide common-mode range (including ground) and low input bias current (25 nA typ). Its output stage is open-collector, requiring external pull-up for logic-level compatibility with CMOS or TTL systems.
Unlike the "A" series variant, HA17393F lacks specified RF immunity enhancements but retains full electrical specifications across −20°C to +75°C operating temperature, with guaranteed performance at VCC = 5 V, 15 V, and 36 V per absolute maximum ratings and electrical characteristics tables.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2 V to 36 V - supports direct operation from 3.3 V, 5 V, 12 V, or 24 V rails without regulation. |
| Supply Current | 0.8 mA typical - enables low-power monitoring in always-on industrial sensors or battery-backed systems. |
| Input Offset Voltage | 2 mV typical - ensures accurate threshold detection in precision voltage monitors or overvoltage protection circuits. |
| Response Time | 1.3 µs - suitable for fast edge detection in pulse-width modulators or motor phase timing. |
| Common-Mode Input Range | Includes ground (0 V) - allows direct connection to shunt resistors or low-side switches without level-shifting. |
| Output Type | Open-collector - enables wired-OR logic, flexible pull-up voltage selection (e.g., 3.3 V or 5 V), and interface with mixed-voltage systems. |
| Input Bias Current | 25 nA typical - minimizes error in high-impedance sensor interfaces such as thermistor or photodiode circuits. |
Pinout & Package
HA17393F-EL-E is housed in the FP-8D package: an 8-pin plastic DIP with 2.54 mm lead pitch, 4.4 mm body width, and 0.10 g mass. Pin 1 is top-left corner (notch side), with standard dual comparator pinout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input of comparator 1 | Accepts reference or feedback signal; supports common-mode down to ground. |
| 2 | Non-inverting input of comparator 1 | Connects to sensed voltage; high impedance (25 nA bias) preserves source accuracy. |
| 3 | Output of comparator 1 | Open-collector - requires external pull-up; sinks up to 16 mA at VCC = 5 V. |
| 4 | GND | Ground reference for both inputs and outputs; shared return path for dual channels. |
| 5 | Inverting input of comparator 2 | Independent channel; identical electrical specs to pin 1. |
| 6 | Non-inverting input of comparator 2 | Independent channel; identical electrical specs to pin 2. |
| 7 | Output of comparator 2 | Open-collector - electrically isolated from pin 3; supports separate pull-up networks. |
| 8 | VCC | Single positive supply input; no negative rail required; decoupling capacitor recommended near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply operation with ground-referenced input | Enables direct low-side current sensing in buck converters or battery management without level shifters. |
| CMOS-compatible open-collector outputs | Allows interoperability with 3.3 V or 5 V logic families via selectable pull-up voltage and supports wired-OR fault signaling. |
| Low 0.8 mA supply current independent of VCC | Reduces standby power in always-on industrial controllers and eliminates supply regulation dependency. |
| 1.3 µs propagation delay at 5 V supply | Supports real-time overvoltage/undervoltage detection in switching power supplies operating up to ~300 kHz. |
| ±2 mV input offset voltage (typ) | Minimizes threshold error in precision window comparators used for battery cell balancing or sensor fault detection. |
Applications
| DC-DC Converter Monitoring | Industrial Overvoltage Protection |
|---|---|

IC Role / Device Role / Timing Role: Precision comparator providing enable signal to MOSFET switch controlling bleed resistor current. Use Value: 25 nA input bias avoids loading high-impedance cell voltage dividers; 2 mV offset ensures ≤10 mV total voltage error. |
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 input offset voltage (7 mV max), wider temp range (−40°C to +85°C), same FP-8D-compatible SOIC-8 package option. | Preferred for extended-temperature industrial designs where HA17393F-EL-E's −20°C lower limit is insufficient. | Select LM393DR when operating below −20°C or requiring higher ESD robustness (2 kV HBM vs. unspecified for HA17393F). |
| TL331IDBVR | Single-channel, SOT-23-5 package, lower supply current (60 µA), but no dual configuration; requires two units for same function. | Suitable for ultra-low-power, space-constrained portable devices-not drop-in replacement for dual-channel use cases. | Choose TL331IDBVR only when redesigning for minimal footprint and sub-100 µA quiescent current is mandatory. |
Compared with LM393DR and TL331IDBVR, HA17393F-EL-E delivers superior input offset (2 mV vs. 7 mV) and ground-sensing capability in a legacy through-hole FP-8D package-making it optimal for cost-sensitive, medium-speed industrial controls where dual channels and proven reliability are prioritized over ultra-low power or extended temperature.

FAQ
What is the operating temperature range for HA17393F-EL-E?
The HA17393F-EL-E is rated for operation from −20°C to +75°C ambient temperature. This range is confirmed in the Absolute Maximum Ratings table on page 4 of the official datasheet (ADE-204-066A Rev. 1). It is narrower than the HA17393APS variant (−40°C to +85°C), reflecting its commercial-grade qualification. Designers must ensure board-level thermal management maintains junction temperature within this envelope.
Does HA17393F-EL-E support rail-to-rail input voltage?
HA17393F-EL-E supports common-mode input voltage down to ground (0 V) but does not support rail-to-rail input swing up to VCC. The datasheet specifies VCM+ = 3.5 V (min) at VCC = 5 V, meaning the upper common-mode limit is typically VCC − 1.5 V. For full rail-to-rail input capability, alternative comparators like the TLC372 or TS393 would be required - HA17393F-EL-E is optimized for ground-referenced sensing, not high-side VCC-near inputs.
What is the maximum sink current capability of HA17393F-EL-E outputs?
The HA17393F-EL-E output can sink up to 16 mA minimum when VIN(−) ≥ 1 V and VIN(+) = 0 V, with VO ≤ 1.5 V (per Electrical Characteristics table, page 5). At 4 mA sink load, output saturation voltage is ≤400 mV. This enables direct driving of LEDs, small relays, or optocouplers without external transistor buffering - a key design advantage for discrete fault-signaling circuits using HA17393F-EL-E.
Is HA17393F-EL-E pin-compatible with LM393?
No, HA17393F-EL-E is not pin-compatible with LM393 in any package variant. While both are dual comparators with open-collector outputs, HA17393F-EL-E uses FP-8D (8-pin DIP) with pin 1 = IN1−, pin 2 = IN1+, pin 3 = OUT1, pin 4 = GND, etc. LM393 in DIP-8 follows a different pinout: pin 1 = OUT1, pin 2 = IN1−, pin 3 = IN1+, pin 4 = GND. Substituting HA17393F-EL-E for LM393 requires PCB layout revision.
What is the typical input offset voltage drift over temperature for HA17393F-EL-E?
The HA17393F-EL-E exhibits input offset voltage drift of approximately ±0.5 mV across its −20°C to +75°C operating range, based on the "Input Offset Voltage vs. Ambient Temperature" curve on page 7 of the datasheet (ADE-204-066A). At 25°C, VIO is 2 mV typical; it rises to ~2.5 mV at −20°C and ~2.4 mV at +75°C. This low drift supports stable threshold performance in unregulated industrial environments without active calibration.
