NCP373MU13TXG

NCP373MU13TXG Description

The NCP373MU13TXG from onsemi is a high-performance overvoltage protection (OVP) controller designed for safeguarding sensitive electronics in handheld and mobile devices. This surface-mount IC operates within a 2.5V to 5.5V supply range, drawing a minimal 200 µA current, making it ideal for power-constrained applications. With an impressive ±28V input voltage tolerance, it provides robust protection against voltage transients. Packaged in a 12-pin TLLGA format and available in Tape & Reel (TR), it suits automated assembly processes. Although marked as Obsolete, its reliability and precision remain valuable for legacy designs.

NCP373MU13TXG Features

• Wide Input Range: Handles ±28V inputs, far exceeding typical OVP ICs.
• Low Power Consumption: 200 µA supply current minimizes energy drain.
• Compact Form Factor: 12TLLGA package saves board space in portable devices.
• MSL1 Rating: Unlimited shelf life with no moisture sensitivity concerns.
• REACH Unaffected: Compliant with environmental regulations.
• Integrated Protection: Guards against both positive and negative voltage surges, a rare dual capability.

NCP373MU13TXG Applications

This IC excels in:

• Mobile Devices: Protects USB ports, batteries, and charging circuits from voltage spikes.
• Industrial Handhelds: Ensures reliability in rugged environments with fluctuating power.
• Legacy Systems: Maintains functionality in older designs requiring obsolete components.
• Automotive Accessories: Safeguards infotainment systems from load-dump transients.

Conclusion of NCP373MU13TXG

The NCP373MU13TXG stands out for its dual-polarity overvoltage protection, low power draw, and compact design. While no longer in production, its ±28V tolerance and 12TLLGA packaging make it a preferred choice for engineers needing robust transient protection in space-constrained, battery-powered applications. Its legacy status underscores the importance of securing remaining stock for critical maintenance or niche designs.
