The SCV301LSN45T1G is a class of PMIC (Power Management Integrated Circuit) Supervisor. This supervisor IC provides robust system protection in a very small package with low power consumption while operating over the industrial temperature range.

The SCV301LSN45T1G is typical employed in industrial, telecom and consumer applications. Its features make it suitable for use in a variety of applications such as printers, computer peripherals, consumer electronics and industrial automation.

The SCV301LSN45T1G packes a combination of system functions into a single 16-pin, 4mm by 4mm TSSOP (Thin Shrink Small Outline Package) that include one reset output, two system power-on resistors, one 400KHz push-pull timer and one low-battery monitor output.

The primary purpose of the SCV301LSN45T1G is providing system reset control and power-on reset resistor control. The reset circuit provides both power-on reset (POR) and power-on sequence resets. The output impedance of the POR circuit is 3.3 ohms to provide an active reset when power is applied. The sequence reset circuit asserts an active reset after a 400KHz clock is detected. The timer circuit allows a sensor to keep the system in reset state until an internal 400KHz oscillation is detected. This feature can be useful in preventing any incorrect behavior of the system due to mishandling during assembly.

The low-battery monitor output is a dedicated open drain output that is asserted active when the system voltage drops below a selectable voltage threshold. This voltage threshold can be programmed between 1.8V and 2.6V.

The SCV301LSN45T1G also provides a low power shutdown function. This feature turns off the supply voltage by pulling the VCC pin low. Additionally, the SCV301LSN45T1G provides a programmable watch-dog timer circuit that can be used to reset the system when a program loop occurs.

The SCV301LSN45T1G also includes an internal power failure monitor circuit that can detect a power failure event and pull the RESET# pin low. The power-failure detection voltage range can be programmed from 1.85V to 2.6V.

The SCV301LSN45T1G can operate over the industrial temperature range from -40 degrees Celsius to +85 degrees Celsius and it is available in a 16-pin TSSOP. It is designed to minimize billing and offer high-value system protection.
