Product details
Overview
HA17903FPJ-E from Renesas is a dual voltage comparator IC designed for automotive and industrial control systems, operating from 2 V to 36 V single supply, drawing only 0.8 mA typical supply current, with 2 mV input offset voltage and rail-to-rail common-mode input range including ground - used in limit detection, pulse generation, and MOS clock timing circuits.
For engineers reviewing the HA17903FPJ-E datasheet, HA17903FPJ-E pinout, HA17903FPJ-E application, or HA17903FPJ-E equivalent, this page delivers verified electrical specs, package mapping to FP-8DGV (P-SOP8), output compatibility with CMOS logic, and real-world design context for automotive-grade analog signal conditioning.
Technical Context
The HA17903FPJ-E integrates two independent comparators with open-collector outputs, each featuring low input bias current (25 nA typ) and low input offset current (3 nA typ), enabling high-impedance sensing in battery-powered or precision threshold-detection applications. Its input stage supports common-mode voltages down to ground, and output saturation voltage is as low as 1 mV at 5 µA sink load.
Designed for wide-temperature operation (–40°C to +125°C), the device maintains stable performance across automotive environments, with supply current independent of VCC and response time of 1.3 µs under 5 V/5.1 kΩ load - suitable for fast edge-triggered timing functions like multivibrators and VCOs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2 V to 36 V single supply - enables direct integration into 12 V/24 V automotive systems without level-shifting. |
| Input Offset Voltage | 2 mV typical - ensures accurate threshold detection within ±2 mV error at room temperature. |
| Supply Current | 0.8 mA typical - minimizes power draw in always-on vehicle subsystems such as door lock monitors. |
| Input Bias Current | 25 nA typical - preserves signal integrity when interfacing with high-impedance sensors or RC timing networks. |
| Output Sink Current | 16 mA maximum - drives standard LED indicators or TTL/CMOS inputs directly without external pull-up resistors. |
| Response Time | 1.3 µs typical - supports reliable pulse-width discrimination up to ~300 kHz in square-wave generators. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive electronics per AEC-Q100-relevant stress profiles. |
Pinout & Package
HA17903FPJ-E is housed in an 8-pin SOP package (JEITA: P-SOP8-4.4×4.85–1.27; Renesas code: PRSP0008DE-B; previous code: FP-8DGV), with gull-wing leads, 1.27 mm pitch, and Ni/Pd/Au plating.
| 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 signals down to ground for single-supply zero-reference comparison. |
| 3 | VIN(+)1 | Non-inverting input of comparator 1 - used for threshold reference or sensor signal routing. |
| 4 | GND | Analog ground reference - shared return path for both comparators and internal bias circuitry. |
| 5 | VCC | Positive supply rail - powers both comparators and supports full 2–36 V operating range. |
| 6 | VOUT2 | Open-collector output of comparator 2 - independently controllable for dual-threshold or window-comparator topologies. |
| 7 | VIN(–)2 | Inverting input of comparator 2 - enables differential or complementary sensing configurations. |
| 8 | VIN(+)2 | Non-inverting input of comparator 2 - supports independent reference setting for second channel. |
Key Features
| Feature | Design Value |
|---|---|
| Wide single-supply range | 2 V to 36 V operation eliminates need for dual supplies or regulators in 12 V/24 V vehicle systems. |
| Ground-sensing input stage | Common-mode input includes 0 V - allows direct interface with sensors referenced to chassis ground. |
| CMOS-compatible output | Output voltage levels meet CMOS logic thresholds - simplifies interfacing with microcontrollers and FPGAs. |
| Low temperature drift | Input offset voltage remains ≤5 mV over –40°C to +125°C - ensures stable trip points in engine bay environments. |

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 input offset voltage (7 mV max), higher supply current (1.2 mA typ), same SOIC-8 package but no automotive temp grade. | Lacks guaranteed operation above +85°C - unsuitable for under-hood automotive use where HA17903FPJ-E supports +125°C. | Select LM393DR only for cost-sensitive industrial controls where extended temperature is not required. |
| TL331IDBVR | Single-channel, SOT-23-5 package, lower supply current (60 µA), but no dual configuration or automotive qualification. | Requires two devices and additional PCB area to replicate dual functionality; lacks AEC-relevant reliability data. | Choose TL331IDBVR only for space-constrained, low-power portable designs - not for dual-channel or automotive applications. |
Compared with LM393DR and TL331IDBVR, HA17903FPJ-E uniquely combines dual-channel architecture, automotive temperature range (–40°C to +125°C), and ground-sensing inputs in a compact SOP-8 package - making it the only option among the three qualified for direct replacement in vehicle body control modules.

FAQ
What is the maximum operating temperature for HA17903FPJ-E?
The HA17903FPJ-E is rated for continuous operation from –40°C to +125°C, meeting requirements for under-hood automotive applications. This specification is confirmed in the Absolute Maximum Ratings table on page 3 of the official datasheet, where HA17903FPJ and HA17903FPK share the +125°C top operating temperature limit.
Does HA17903FPJ-E support rail-to-rail input operation?
HA17903FPJ-E supports common-mode input voltage down to ground (0 V), but not up to VCC. The datasheet specifies VCM– = 0 V and VCM+ = VCC – 2.0 V (max) at temperature extremes - meaning the upper input limit is 2 V below VCC, not rail-to-rail. This allows ground-referenced sensing but requires margin at the high end.
Is HA17903FPJ-E pin-compatible with HA17903PSJ?
No, HA17903FPJ-E is not pin-compatible with HA17903PSJ. HA17903FPJ-E uses the FP-8DGV (P-SOP8) package with 1.27 mm pitch, while HA17903PSJ uses DP-8B (DIP-8) with 2.54 mm pitch. Pin numbering matches per the top-view diagram, but physical layout, thermal characteristics, and board footprint differ significantly.
Can HA17903FPJ-E drive a 5 V CMOS load directly?
Yes, HA17903FPJ-E outputs are compatible with CMOS logic systems. Its open-collector outputs can sink up to 16 mA, and with a properly sized external pull-up resistor to 5 V, it reliably asserts logic-high and logic-low levels meeting standard CMOS input thresholds - confirmed in the "Features" section and Electrical Characteristics tables.
What is the typical input offset voltage of HA17903FPJ-E at room temperature?
The typical input offset voltage of HA17903FPJ-E at 25°C and VCC = 5 V is 2.0 mV, with a maximum of 5.0 mV across temperature and process variation. This value is explicitly listed in the "Electrical Characteristics-1" table on page 3 of the datasheet under the VIO parameter.
