LM2903HYPT

LM2903HYPT Description

The LM2903HYPT from STMicroelectronics is a dual general-purpose comparator designed for automotive and industrial applications. Packaged in an 8-pin TSSOP and supplied in Tape & Reel (TR), it operates over a wide voltage range (2V to 36V single supply, ±1V to ±18V dual supply). This device is ROHS3 compliant and REACH unaffected, ensuring environmental and regulatory compliance. With a low input bias current (0.25µA @ 5V) and quiescent current (max 2.5mA), it is optimized for power-sensitive designs. Its automotive-grade qualification makes it suitable for harsh environments.

LM2903HYPT Features

• Dual Comparator Configuration: Two independent comparators in a single package, reducing board space.
• Wide Supply Range: Supports 2V–36V (single) or ±1V–±18V (dual), ideal for battery-powered and industrial systems.
• Low Power Consumption: Quiescent current ≤2.5mA and input bias current ≤0.25µA, enhancing efficiency.
• High Output Drive: 16mA sink capability @ 5V, enabling direct LED or relay driving.
• Robust Performance: 7mV max input offset voltage ensures precision in comparison tasks.
• Automotive-Grade Reliability: Meets stringent automotive standards for temperature and durability.
• Surface-Mount Package (TSSOP-8): Compact footprint for space-constrained applications.

LM2903HYPT Applications
