A Supervisor Integrated Circuit is a type of power management integrated circuit (PMIC) designed to monitor the power supply and other operating conditions, such as output voltage and temperature, of a system. These devices provide a variety of features, such as automatic power-on and power-off control, input voltage detection and other fault protection operations to ensure system stability and safety. The CAT1163WI28 is a PMIC supervisor designed and manufactured by Integrated Device Technology, Inc. (IDT). It is a low-cost and low-power solution who supervisory functions cover extended system operation.

The CAT1163WI28 is a single-channel supervisor IC that provides power-on reset, power-off reset, brown-out reset and low-battery monitor using an external voltage source. The device operates in an extended operating temperature range from -40°C to +85°C and is ideal for applications such as industrial, automotive and telecommunications. The CAT1163WI28 also has an integrated watchdog timer that can detect system lockups. The device is available in 3-pin SOT23-5 packages.

The CAT1163WI28 is configured as a reset circuit for low-power applications. The device has an internal bandgap reference that provides a preset threshold voltage (VTR). The prescribed voltage can be adjusted through external resistors to set the operating voltage. When the system voltage drops below the threshold voltage, the reset circuit triggers the reset output to alert the system.

The CAT1163WI28 has several features that help protect the system from over-voltage and over-temperature events. The device can detect input voltage levels between 1.8 V and 5.3 V and also has an adjustable input reset delay of up to 100 ms. The device also has a programmable temperature sensor threshold (TTH) that triggers a reset in case of excessive temperature. The CAT1163WI28 also has an LED indicator for visual alert.

The CAT1163WI28 offers a wide range of applications. It can be used in a number of applications such as motor controllers, solar panel power controllers as well as industrial, automotive and telecommunications applications. The device is also suitable for monitoring standby voltage and battery discharge situations, making it an ideal choice for Li-Ion battery monitoring. The device addresses the need of low-power applications to provide reliable power-on functions.

In summary, the CAT1163WI28 is a low-cost and low-power supervisor IC with integrated reset and watchdog functions. The device provides power-on reset, power-off reset, brown-out reset and low-battery monitor using an external voltage source and can detect input voltage levels from 1.8 V to 5.3 V. The device is also suitable for motor controllers, solar panel power controllers, Li-Ion battery monitoring and other applications that require reliable power-on functions and system safety.
