The CAT1640YI42 is a low-power voltage supervisor, primarily intended for PMIC applications. It is designed to monitor voltage levels on a wide range of applications, such as embedded system, servers and storage subsystems. It is used to ensure that the power system remains in a stable state and provides a wide range of protection functions, such as brown out protection, thermal protection, and over voltage protection.
Application Field
The CAT1640YI42 is a versatile low-power voltage supervisor, designed for a wide range of voltage supervision applications. It is suitable for monitoring voltage levels in embedded systems such as MCUs, memory, analog and digital components, disk drives and FPGAs. Additionally, the CAT1640YI42 can be used for over voltage protection in servers, workstations and storage subsystems. The device is available in a 4-pin PDSO or SOIC package, making it highly suitable for small to medium-sized systems.
Working Principle
The CAT1640YI42 low-power voltage supervisor operates on a simple two threshold principle. It features two voltage thresholds, a fixed threshold (Vf) and an adjustable threshold (Vadj). The Vf threshold typically is set at 1.9 V and is designed to provide first-level protection for the system. The Vadj threshold is an adjustable threshold that starts at 1.2 V and can be adjusted up to 1.8 V in 0.01V increments for second level protection. When the voltage falls below either the Vf or Vadj thresholds, the CAT1640YI42 will generate an active-low signal to the system, to indicate that the voltage has fallen below the set level.
The CAT1640YI42 also integrates advanced power-saving measures to reduce its power consumption. It features an auto-sleep mode which reduces its power consumption to 10 micro-amps and a self-forward delay feature which delays the output signal, reducing it to an 80 micro-amp current. The device also features built-in clock cycle control, which allows the device to enter sleep mode after selected clock cycles.
The CAT1640YI42 integrates several protection functions to provide robust system-level protection. It features latching voltage protection, which will protect the system in case of over voltage occurrences. Additionally, it features thermal protection, which limits the amount of power that the device can draw from the system, and a brown out protection, which will protect the system from low voltage conditions.
Conclusion
The CAT1640YI42 is a versatile low-power voltage supervisor, offering a range of protection and power saving features for PMIC applications. It uses a two threshold principle and integrates several protection functions for reliable system-level protection. It is available in a 4-pin package and is suitable for controlling voltage levels in embedded systems as well as servers and storage subsystems.
