What are the key features of PLM2903EPWRQ1?
- AEC-Q100 Grade 0 and Grade 1 automotive qualification ensuring reliable operation across harsh temperature ranges from -40°C to 150°C
- Dual differential comparator with open-collector outputs supporting wired-OR bus configurations and direct pull-up to higher voltage rails
- Ultra-low input bias current of 0.25 µA maximum at 25°C minimizing loading on high-impedance sensor signal sources
- High-voltage input range enabling direct comparison of automotive battery-level signals without external voltage dividers in 12V or 24V systems
What is PLM2903EPWRQ1 used for?
The PLM2903EPWRQ1 is designed for automotive body control modules, ADAS sensor interfaces, and battery management systems where AEC-Q100 Grade 0 or Grade 1 reliability is mandatory. Its dual comparator architecture handles two independent threshold detection tasks simultaneously — for example, comparing a battery voltage divided signal against a reference while monitoring a temperature sensor output on the second channel. The open-collector output topology allows multiple PLM2903EPWRQ1 outputs to be wire-OR connected for fault-flag aggregation in automotive ECUs.

Frequently Asked Questions
What AEC-Q100 qualification grades does the PLM2903EPWRQ1 hold, and what temperature range does that correspond to?
The PLM2903EPWRQ1 carries AEC-Q100 Grade 0 and Grade 1 qualification. Grade 0 covers an ambient temperature range of -40°C to 150°C, the most demanding automotive tier for under-hood and powertrain applications. Grade 1 covers -40°C to 125°C for general automotive body and interior use. Holding both grades makes the device interchangeable across multiple ECU design families without re-qualification.
How does the open-collector output of the PLM2903EPWRQ1 benefit fault-flag wiring in automotive ECUs?
Open-collector outputs can be wire-OR connected, meaning multiple PLM2903EPWRQ1 comparator outputs can share a single pull-up resistor and fault-flag line. If any comparator detects an out-of-range condition, it pulls the shared line low, signaling a fault to the MCU without additional logic gates. This simplifies fault aggregation in automotive ECUs monitoring multiple analog channels such as current sense signals, temperature sensors, and voltage rails simultaneously.
What is the maximum input bias current of the PLM2903EPWRQ1, and why does that matter for high-impedance automotive sensor inputs?
The PLM2903EPWRQ1 specifies a maximum input bias current of 0.25 µA at 25°C and an average of 0.05 µA. For high-impedance automotive sensors — such as resistive temperature detectors or NTC thermistors with source impedances in the 10 kΩ to 100 kΩ range — a 0.25 µA bias current causes at most a 2.5 mV to 25 mV voltage error, keeping measurement accuracy within acceptable bounds without additional buffering stages.
In a 12V automotive battery monitoring circuit, how does the PLM2903EPWRQ1 compare two voltage thresholds simultaneously?
Using both of its 2 differential comparator channels, the PLM2903EPWRQ1 can simultaneously compare a divided battery voltage against an under-voltage threshold on channel 1 and an over-voltage threshold on channel 2. With a resistive divider bringing a 12V rail into the valid input range, both channels monitor the battery in a single 8-pin SOIC package, flagging under-voltage or over-voltage conditions via separate open-collector outputs connected to the ECU microcontroller's GPIO interrupt pins.
