NCP305LSQ35T1G is a precision microprocessor reset and watchdog supervisor family which provides system reset, as well as push-button reset protection, built-in power-fail detect, temperature monitoring and an optional watchdog timer. The NCP305LSQ35T1G is a line of supervisors that have low operating current and extraordinarily low supply current. It includes fixed reset thresholds to ensure the reset signal stays active for a defined time period. This enables the supervisor to maintain accurate centralized control of various complex system power-on reset, power-fail reset and watchdog functions.

NCP305LSQ35T1G is widely used in consumer electronics, industrial equipment, automotive electronics, audio-video and other systems that require precision reset or watchdog functions. This microprocessor reset and watchdog supervisor family are ideal for applications such as computers and peripherals, communication devices, consumer electronics, automated industrial systems, embedded control systems and other applications that require monitoring and power management. The NCP305LSQ35T1G also offers protection for a series of hot-swap/brown-out, power-down reset, watchdog timers, and over voltage and temperature resistant conditions.

The operating current for the NCP305LSQ35T1G is typically 22 µA with a supply current under normal operation of 1 µA. It can support a voltage range from 2.7V to 5.5V and has a low reset threshold of 2.7V. It also features brown-out detection triggered at 5%, 10%, 15%, 20%, 25%, and 30% below the normal operating voltage. The reset output is guaranteed to remain active for at least 100 ms.

The NCP305LSQ35T1G family features the Brown-Out Reset (BOD) circuit to guard against power supply glitches by issuing a reset on a power supply initially below the set threshold. In addition to the reset outputs, supply voltage and temperature, an optional Watchdog Timer is also available.

To summarize, the NCP305LSQ35T1G is a low power microprocessor reset and watchdog supervisor family that is ideal for a wide variety of applications. It features low operating and supply currents, very stable reset characteristics and a wide operating voltage range. The NCP305LSQ35T1G family provides system reset and push-button reset protection, brown-out detection triggered at 5%, 10%, 15%, 20%, 25%, and 30% below the normal operating voltage. It also includes an optional watchdog timer for system monitoring and event control.
