PMIC - Supervisors

PMIC (power management integrated circuit) supervisors provide power supply reset signals to ensure that a system has a safe power path as it powers up and powers down. They also provide an active low power-on reset (POR) signal that a microcontroller or processor can use to properly start up. A supervisor can sense voltage levels, brown out conditions and over temperature conditions. They are designed to provide a margin of safety for abnormal conditions at the system startup.

CAT1163WI-42-G is a micro power voltage supervisor IC capable of providing reset switch operation when a condition of undervoltage or overvoltage appears on its outputs. This device performs a high level of monitoring as it continuously checks the voltage level at its individual outputs. The device also has a reset pin input that can be used to provide a reset pulse.

CAT1163WI-42-G Application Field and Working Principle

The CAT1163WI-42-G micro power voltage supervisor is a two-channel device which provides an accurate reset switch operation when a system power supply is undershoot or overshoot. The device integrates an over voltage protection circuit that it uses to detect any voltage cracks and provides an output flag that can be used to inform the system of a power supply failure. With its two enable input states and its wide supply voltage range, the CAT1163WI-42-G makes it possible to control the delay times of the two outputs separately.

The CAT1163WI-42-G device is designed to be used in a variety of electronic systems. It can be used for monitoring a main power supply DC/DC converter circuit during the startup phase, and can also be used in security computer systems such as an encryption circuit that always needs an uninterrupted power supply. Furthermore, the reset circuit of the CAT1163WI-42-G can also be utilized in a wide range of embedded systems, from automotive to white goods applications.

The CAT1163WI-42-G operates through a simple wiring of its inputs and outputs. The device has two main input functional blocks, the input voltage range block and the open-drain output block. The input voltage range block has two pins, VH and VL, that are used to set the upper and the lower input voltage level limit levels between 2.9V to 5.5V.

The open-drain output block is composed of two pins, RSTO and RSTI. The RSTO output is an open-drain reset output that is triggered when the input voltage of VH/VL falls below or is above the set limit levels. This output can also be pulled down by the RSTI input if a reset pulse is present. When triggered, the RSTO reset state is latched and can only be reset if the reset button is pressed. The CAT1163WI-42-G also has a RESET input pin that can be used for manual resetting of the IC. Upon the reset, the device resumes its normal operation.

The CAT1163WI-42-G comes in a small SOT23-5L package and usually has a rated current of 10 mA and a power dissipation of 5000 mW. It can also operate across a wide temperature range of -40°C to +125°C. Additionally, it is also AEC-Q100-qualified, making it an ideal choice for use in automotive systems.

In conclusion, the CAT1163WI-42-G is a two-channel micro power voltage supervisor that can provide accurate reset switch operations whenever overvoltage, undervoltage, or brownout conditions occur in a system. With its wide temperature range and low power dissipation, it is ideal for use in a variety of embedded systems and automotive applications. It also has built-in overvoltage protection and manual reset capability that make it a robust and reliable choice for system protection.
