SP706SEU-L/TR

PMIC, or Power Management Integrated Circuits, are an important component in any modern electronics system or device. They perform a variety of different tasks, from controlling the amount of power supplied to a device, to providing low stand-by current and power-saving features. Supervisors are a type of PMIC that provide a redundant system for monitoring voltage levels, detecting faults, and providing shut-down protection. One example of a such a Supervisor is the SP706SEU-L/TR.

The SP706SEU-L/TR is a high-performance SmartGuard supervisor IC designed for use in desktop and mobile consumer electronics, networking, and automotive applications. It provides high precision, low-power monitoring of the power supply and system power-on/off signals, battery backup, and a watchdog timer. The SP706SEU-L/TR is optimized to monitor two power supply voltages simultaneously, though it also provides support for monitoring a single power supply. It offers four programmable undervoltage thresholds and two programmable overvoltage thresholds, with accurate trip points and extended temperature range support.

The SP706SEU-L/TR is designed to detect voltage faults and provide power-on reset, reset device status registers and isolate the system bus. It also monitors auxiliary supply inputs, detects low-current conditions, supplies bias to other devices, and reports system status and status changes through an adjustable-threshold comparator. It has an integrated watchdog timer with its own time base, making it ideal for use in failure-protection scenarios. The device supports both active-high and active-low reset and can be used in both single-pulse sequential boot-up and single-pulse simultaneous boot-up modes.

The SP706SEU-L/TR is based on a thermally enhanced 2.8V-5V CMOS technology and provides high accuracy, low power consumption and improved system reliability. It features two undervoltage thresholds and two overvoltage thresholds, with an adjustable-threshold comparator for easy monitoring of user-defined system operation margins.
