Product details
Overview
UPC177G2(3)-E1-A from Renesas Electronics is a single-supply quad comparator IC with open-collector outputs, ±2 mV typical input offset voltage, 1.3 µs pulse response time, and operation from +2 V to +32 V supply. It serves as a voltage comparison engine in industrial control logic, power supply monitoring, and threshold detection circuits where rail-to-rail input common-mode range (0 V to V+−1.5 V) and wired-OR capability are required.
For engineers reviewing the UPC177G2(3)-E1-A datasheet, UPC177G2(3)-E1-A pinout, UPC177G2(3)-E1-A application, or UPC177G2(3)-E1-A equivalent, this page delivers verified electrical parameters, SOP-14 package mapping, real-world use scenarios, and two confirmed alternative comparators for design flexibility under single-supply constraints.
Technical Context
The UPC177G2(3)-E1-A implements four independent PNP-input comparators in a single monolithic IC, enabling simultaneous multi-threshold evaluation without cross-channel interference. Its input stage operates down to V− (GND), supports differential input voltages up to ±36 V, and delivers 16 mA sink current per output - sufficient to directly drive LEDs, relays, or TTL/CMOS inputs.
Designed for communication industry applications, it specifies −40 °C to +85 °C operating ambient temperature and features low 0.8–2 mA quiescent current. The open-collector outputs allow flexible pull-up configuration and hardware-level OR-ing of multiple comparator outputs without external logic gates.

| Low quiescent current | 0.8–2 mA total ICC supports always-on monitoring in energy-constrained systems such as remote telemetry nodes |
Applications
| Industrial Power Sequencing | Battery Voltage Monitoring |
|---|---|
Use Scenario: Verifying correct turn-on order of multiple DC rails (e.g., 12 V, 5 V, 3.3 V) in programmable logic controllers before enabling FPGA configuration. IC Role / Device Role / Timing Role: Quad comparator simultaneously compares each rail against its reference voltage to generate individual enable flags. Use Value: Eliminates need for four discrete comparators or microcontroller ADC polling - reduces BOM count and improves deterministic startup timing. | Use Scenario: Detecting low-battery condition (< 3.0 V) and over-voltage risk (> 4.3 V) in portable medical devices powered by Li-ion cells. IC Role / Device Role / Timing Role: Two comparators monitor cell voltage against precision references; outputs feed OR-gated interrupt line to MCU. Use Value: Achieves sub-10 mV detection accuracy with no software overhead, extending runtime while ensuring safety-critical shutdown. |
| Motor Overcurrent Protection | Optical Sensor Threshold Detection |
Use Scenario: Shutting down H-bridge drivers when shunt voltage exceeds 100 mV (indicating >5 A load current) in automated gate actuators. IC Role / Device Role / Timing Role: One comparator channel compares amplified shunt voltage to fixed reference; output triggers latch circuit. Use Value: 1.3 µs response ensures fault detection occurs within one PWM cycle - preventing MOSFET thermal runaway. | Use Scenario: Converting analog output from ambient light sensor into digital ON/OFF signal for automatic streetlight control. IC Role / Device Role / Timing Role: Comparator converts linear photodiode current into clean logic-level output with hysteresis to prevent flicker near threshold. Use Value: Built-in open-collector output simplifies hysteresis implementation using feedback resistor - no external op-amp needed. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339DR | Higher input offset (±2.5 mV max), slower response (1.3 µs typ but 3 µs max), wider temp range (−40 °C to +125 °C) | Qualified for automotive underhood use; less precise for low-voltage thresholding | Select LM339DR when extended temperature range or AEC-Q200 qualification is required, not for precision <5 mV thresholds |
| TLV339IPW | Lower supply range (+1.6 V to +5.5 V), rail-to-rail input, CMOS output (push-pull), 350 ns response | Optimized for ultra-low-voltage battery-powered systems; incompatible with >5.5 V supplies | Choose TLV339IPW only for sub-3.3 V designs requiring push-pull output and nanosecond response - not for 12/24 V industrial use |
Compared with LM339DR and TLV339IPW, UPC177G2(3)-E1-A uniquely balances wide supply tolerance (+2 V to +32 V), industrial temperature rating, and ±2 mV offset - making it optimal for cost-sensitive, single-supply 5–24 V embedded systems needing reliable analog thresholding without microcontroller intervention.

FAQ
What is the maximum supply voltage rating for UPC177G2(3)-E1-A?
The absolute maximum supply voltage (V+ − V−) for UPC177G2(3)-E1-A is +36 V. However, the recommended operating range is +2 V to +32 V. Exceeding +36 V risks permanent damage due to internal junction breakdown, and operation above +32 V voids guaranteed electrical performance per the datasheet. Always include margin for transient spikes in real-world 24 V systems.
Does UPC177G2(3)-E1-A support dual-supply operation?
Yes, UPC177G2(3)-E1-A supports dual-supply operation with V± ranging from ±1 V to ±16 V. Its input common-mode range extends to V− − 0.3 V, and the open-collector outputs remain functional with V− referenced to a negative rail. This allows use in traditional op-amp-style configurations where both rails are non-zero.
Can unused comparator sections in UPC177G2(3)-E1-A be left floating?
No - unused comparator inputs must not be left floating. Per Renesas' datasheet guidance, tie both IN and II pins of inactive sections to a defined potential within the common-mode range (e.g., V− or mid-supply via resistor divider). Floating inputs cause unpredictable output states and increased supply current due to internal PNP input stage bias instability.
What is the purpose of the E1 suffix in UPC177G2(3)-E1-A?
The E1 suffix indicates embossed tape packaging with pin 1 located on the draw-out side of the reel. This mechanical orientation is critical for automated pick-and-place machines during SMT assembly. E1 differs from E2 (pin 1 at take-up side); using the wrong orientation causes placement errors and potential tombstoning during reflow.
How does the input bias current behavior differ between balanced and active comparator states in UPC177G2(3)-E1-A?
In the balanced state (e.g., during offset measurement), input bias current is 25 nA (typical) flowing out of both IN and II pins. During active comparison, however, current flows twice as strongly - ~50 nA - toward the lower-potential input pin due to unbalanced PNP input stage conduction. This asymmetry must be considered when designing high-impedance reference networks.
