LM2903WYPT

Overview

The LM2903WYPT is a low-power dual voltage comparator manufactured by STMicroelectronics, designed for operation from a single supply over a wide voltage range. It features two independent comparators with an input common-mode voltage range that includes the negative rail. The device operates within a supply voltage range of +2 V to +36 V or ±1 V to ±18 V. Key electrical characteristics include a very low supply current of 0.4 mA, independent of supply voltage, and a typical input bias current of 25 nA. The output saturation voltage is typically 250 mV at an output current of 4 mA. The component is automotive qualified under AEC-Q100 standards and is available in a TSSOP-8L package.

Feature Summary

• Wide single supply voltage range or dual supplies capability
• Very low supply current independent of supply voltage
• Input common-mode voltage range includes negative rail
• Automotive qualification compliant

Applications

• Automotive sensor signal conditioning
• Industrial control systems
• General-purpose voltage monitoring

Procurement Notes

Verify the specific suffix WYPT against official STMicroelectronics documentation to confirm the TSSOP-8L package and automotive grade status. Ensure compatibility with system requirements for supply voltage, input bias current, and output drive capabilities before procurement. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when low power consumption and wide supply voltage operation are required in automotive or industrial environments. Consider the LM2903W if higher ESD performance is needed, or the LM2903H for applications requiring operation up to 150°C. Evaluate the trade-off between the standard LM2903 and this variant based on package availability and specific automotive qualification requirements.

Part Context

The LM2903 series consists of dual low-power voltage comparators designed for single-supply operation. The LM2903WYPT variant specifically denotes the automotive-grade version in a TSSOP-8L package. This family is characterized by its ability to operate from a wide range of supply voltages while maintaining low power dissipation, making it suitable for battery-powered and space-constrained applications.

Replacement Considerations

The LM2903W is noted as a similar device with higher ESD performances. The LM2903H is mentioned for applications requiring operation up to 150°C. Verify pinout and electrical specifications before substituting.
