NCV301HSN27T1G

NCV301HSN27T1G is a fixed-threshold voltage supervisor (reset IC) from ON Semiconductor. It monitors the supply voltage (Vcc) and asserts a reset to a microcontroller or digital logic when Vcc falls below its fixed 2.7 V threshold, and keeps reset active during power‑up/power‑down until the rail is stable. It offers fast reset response with low quiescent current, making it suitable for battery-powered and low-voltage systems. The part name indicates a 2.7 V threshold (27) and a compact HSN package (T1G). Applications include MCU/SoC supervision, brown‑out protection, and any circuit needing a defined reset on supply fluctuations. For precise electrical specs, timing, reset polarity, pinout, and packaging, consult the NCV301HSN27T1G datasheet.

I don’t have the NCV301HSN27T1G datasheet memorized. Want me to fetch the official datasheet and list its features? I can provide a concise bullet list (e.g., operating voltage range, reset/output behavior, timing specifications, current consumption, temperature range, package type).

- Pin count: 8 pins (8-pin package, e.g., MSOP8/SO-8).
- Function: Automotive high-side switch IC with an integrated MOSFET. It switches a load to the supply and provides protection (current limit, thermal/shutdown, reverse/short-circuit protection) with control inputs (IN/EN) and a diagnostic/status output (DIAG) or similar. Power is supplied to VCC/VBAT, with a GND reference.

- Manufacturer: ON Semiconductor (ON Semiconductor Corporation), also known as Onsemi.
- What kind of company: An American multinational semiconductor company that designs and manufactures energy-efficient integrated circuits and discrete devices for automotive, industrial, communications, and consumer electronics markets.

NCV301HSN27T1G is a TVS/ESD protection device. Typical applications include:
- Automotive and industrial 12–24V rails protection against transients (surges, load dumps, reverse polarity)
- Protection of data/control interfaces (CAN, LIN, RS-485, USB, Ethernet)
- ESD/surge protection for sensors, MCUs, and I/O connectors
- Input protection for DC–DC converters and battery-management circuits
- General line protection in 24V/27V systems and other high-voltage logic interfaces
