Power management integrated circuit (PMIC) supervisors are used in a wide variety of applications to help ensure system reliability. The CAT1162WI-42-T3 is a PMIC supervisor that is designed to provide precision voltage monitoring and system level control. It provides a reliable, cost-effective solution for a variety of design needs.

The CAT1162WI-42-T3 provides a variety of voltage monitoring, sequencing, and reset options that can be tailored to provide system safety and stability. The supervisor\'s versatile design allows it to support a wide variety of voltage thresholds and timing circuits. Its integrated low voltage power-on reset (LV POR) circuit provides accurate device initializing for start-up, hot swap, and continuing device initialization.

The CAT1162WI-42-T3 features a wide operating temperature range that can support applications in harsh environments. It also provides a regulated output voltage monitor for power on detection and system reset management. Its integrated high voltage power-on reset (HVPOR) can be configured to detect rising and/or falling overvoltage conditions, providing system reset and alert features. The supervisor can additionally be configured with an open drain reset output that can be used as an input to other system reset circuits.

The CAT1162WI-42-T3 can be configured to provide numerous fault conditions that can be used to support system safety and recoverability. It supports fault assertion based on time or voltage thresholds, or on the detection of particular logic levels or conditions on its discrete inputs. Fault and alert signals can be latched in memory and asserted at reset and/or alarm level output pins. They can also be debounced and masked to eliminate false indications and maximize system resilience.

The CAT1162WI-42-T3 provides additional beofit as an input voltage monitor, allowing monitoring of system and supply voltages in order to detect overservices and support system safety functions. An integrated 6-bit ADC is included for monitoring, and can be read by the host processor for evaluation and/or reset conditions. Its versatile design allows for up to eight separate input channels that can be programmed for over-voltage and/or under-voltage detection.

The CAT1162WI-42-T3 can be programmed to provide a wide range of fault conditions including power-on reset (POR), brown-out reset (BOR), watchdog timer (WDT), power-good (PGood), Over/Under Voltage (OVP/UVP) and Undervoltage Lock Out (UVLO) conditions or combinations thereof. The integrated time selectable watchdog timer can be configured with multiple time-out intervals and can be used to reset the system when a fault or error condition occurs.

The CAT1162WI-42-T3 provides a cost-effective, reliable and integrated PMIC supervisor solution with a variety of capabilities. Its wide range of voltage monitoring, sequencing and reset options provide system-level control and can help to ensure system reliability and stability. Its integrated reset and alarm features also support system safety and fault detection, providing improved system resilience and recoverability.
