Product details
Overview
HA17903PS-01-E from Renesas is a dual voltage comparator IC designed for automotive and industrial control systems, operating from 2V to 36V single supply, with 0.8mA typical supply current, 2mV input offset voltage, and rail-to-rail common-mode input range including ground - used in limit detection, analog-to-digital conversion, and pulse generation circuits.
For engineers reviewing the HA17903PS-01-E datasheet, HA17903PS-01-E pinout, HA17903PS-01-E application, or HA17903PS-01-E equivalent, key selection considerations include wide supply voltage tolerance, low input bias current (25nA), CMOS-compatible output logic level, and guaranteed operation from –40°C to +85°C in DIP-8 package.
Technical Context
The HA17903PS-01-E integrates two independent comparators with open-collector outputs, each featuring matched input transistor pairs and internal biasing optimized for stable performance across temperature and supply voltage variations. Its differential input stage supports common-mode voltages down to ground, enabling direct sensing of low-side current shunts or battery monitoring signals.
It delivers 1.3µs typical response time at 5V supply with 5.1kΩ load, and maintains output sink capability up to 16mA while holding saturation voltage below 400mV at 4mA load - critical for driving TTL/CMOS logic or discrete MOSFET gates without external pull-ups.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2V to 36V - enables direct use with 12V automotive batteries or 24V industrial rails without regulation |
| Input Offset Voltage | 2mV typ - ensures accurate threshold detection in precision window or zero-crossing applications |
| Input Bias Current | 25nA typ - minimizes error in high-impedance sensor interfaces (e.g., thermistors, photodiodes) |
| Response Time | 1.3µs typ - supports fast edge detection in pulse-width modulation or timing generator circuits |
| Output Sink Current | 16mA max - drives standard LED indicators, small relays, or logic inputs directly |
| Operating Temperature | –40°C to +85°C - qualified for under-hood automotive and factory-floor industrial environments |
| Common-Mode Input Range | 0V to VCC–2V - allows ground-referenced input signal conditioning without level-shifting circuitry |
Pinout & Package
HA17903PS-01-E is housed in an 8-pin plastic DIP (Dual In-line Package) with JEITA code P-DIP8-6.3x9.6-2.54 and Renesas code PRDP0008AF-A, featuring through-hole mounting and 2.54mm pin pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Vout1 | Open-collector output of Comparator 1 - requires external pull-up for logic-high assertion |
| 2 | Vin(–)1 | Inverting input of Comparator 1 - accepts reference or feedback signal for threshold comparison |
| 3 | Vin(+)1 | Non-inverting input of Comparator 1 - connects to sensed signal for active-high output behavior |
| 4 | GND | Analog ground reference - shared return path for both comparators and supply decoupling |
| 5 | VCC | Positive supply terminal - powers both comparators from single 2–36V source |
| 6 | Vin(+)2 | Non-inverting input of Comparator 2 - enables dual-threshold or window comparator configurations |
| 7 | Vin(–)2 | Inverting input of Comparator 2 - supports independent reference setting per channel |
| 8 | Vout2 | Open-collector output of Comparator 2 - electrically isolated from Vout1 for independent load control |
Key Features
| Feature | Design Value |
|---|---|
| Wide single-supply operation | 2V to 36V range eliminates need for dual-rail supplies in battery-powered or industrial systems |
| Low input bias current | 25nA typical enables high-impedance sensor interfacing without significant loading error |
| Ground-sensing input stage | Common-mode range includes 0V - supports direct connection to shunt resistors or grounded sensors |
| CMOS-compatible output logic | Output voltage swing matches CMOS input thresholds - simplifies interface with microcontrollers and FPGAs |
| Temperature-stable performance | Specified input offset and supply current over –40°C to +85°C - reduces calibration burden in harsh environments |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM393DR | Wider temp range (–40°C to +125°C), higher input offset (7mV max), 2.5mA max supply current | Better suited for extended-temperature industrial modules where HA17903PS-01-E's +85°C limit is insufficient | Select LM393DR when ambient exceeds 85°C or when higher output sink current (25mA) is required |
| TLV3702IDR | Rail-to-rail input/output, 1µA supply current, 3.5mV offset, but limited to 16V max supply | Ideal for low-power battery-operated devices needing precision near supply rails, not automotive 24V+ systems | Choose TLV3702IDR only for sub-16V, ultra-low-power designs where HA17903PS-01-E's 36V range is unnecessary |
Compared with LM393DR and TLV3702IDR, HA17903PS-01-E uniquely balances 36V operation, automotive-grade temperature rating, and 2mV offset in DIP-8 - making it optimal for cost-sensitive, high-voltage, ground-referenced sensing where space permits through-hole packaging.

FAQ
What is the maximum supply voltage rating for HA17903PS-01-E?
The absolute maximum supply voltage for HA17903PS-01-E is 36V, as specified in the Absolute Maximum Ratings table. Operation beyond this voltage risks permanent device damage. The comparator functions reliably across its full 2V to 36V recommended range, making HA17903PS-01-E suitable for unregulated 24V industrial rails and 12V automotive systems where transient spikes may occur.
Does HA17903PS-01-E support input signals referenced to ground?
Yes, HA17903PS-01-E supports common-mode input voltages down to 0V (ground), as confirmed by the "Common mode input voltage range including ground" feature and Electrical Characteristics table listing VCM– = 0V. This allows direct connection of sensors or shunt resistors to either comparator input without level-shifting circuitry - a key design advantage in battery monitoring and current-sense applications using HA17903PS-01-E.
What is the output configuration of HA17903PS-01-E?
HA17903PS-01-E features two open-collector outputs (Vout1 and Vout2), each capable of sinking up to 16mA. These outputs require external pull-up resistors to define the logic-high voltage level and are compatible with TTL and CMOS logic families. The open-collector structure enables wired-OR logic, level translation, and direct drive of LEDs or small relays - essential functionality implemented in HA17903PS-01-E's dual-comparator architecture.
Is HA17903PS-01-E qualified for automotive applications?
Yes, HA17903PS-01-E is explicitly designed for car use, as stated in the official Renesas datasheet description and Ordering Information table. It is rated for operation from –40°C to +85°C and packaged in the PRDP0008AF-A (DP-8B) DIP format, meeting mechanical and thermal requirements for under-dash automotive electronics. This qualification makes HA17903PS-01-E appropriate for ECU subsystems, lighting controls, and battery management where reliability under vibration and temperature cycling is critical.
What is the typical input offset voltage of HA17903PS-01-E?
The typical input offset voltage of HA17903PS-01-E is 2.0mV at 25°C and 5V supply, with a maximum of 5.0mV over the full operating temperature range (–40°C to +125°C). This low offset enables accurate threshold detection in precision applications such as window comparators and analog-to-digital conversion stages - a defining specification confirmed across multiple test conditions in the HA17903PS-01-E datasheet.
