The DS1708SEPA+ is a member of the Supervisors family of Power Management Integrated Circuits (PMIC) , and is particularly suited for systems that require a battery backup supervisory function. The DS1708SEPA+ is a low-cost, low-power device with high accuracy features, such as precision voltage and temperature monitoring, to ensure reliable operation of portable applications. The DS1708SEPA+ offers excellent user flexibility in the form of device options, including the choice of temperature sensing options, a signal output type, a clock frequency, alarm settings, and a power supply voltage range.

The DS1708SEPA+ is designed to monitor voltage for signals ranging from 1.7V to 5.5V, and is capable of accurately detecting signals down to 1.25V and up to 8V due to its low 1.5V Dropout Voltage (DOWNV). Additionally, the device features an integrated temperature sensor (LT, IT, RT, or FT), which can detect and output an analog signal proportional to the temperature. The device then outputs a low-voltage signal depending on the settings configured by the user, to indicate an undervoltage, temperature warning, or other condition, thereby providing an essential backup function for battery-powered systems.

The DS1708SEPA+ also features a small package size and low current draw to suit a wide range of small form factor, battery-powered electronics. The device is constructed in a 1-pin SC-70 package, which is a surface- mounted, ultra-small footprints. The device operates at frequencies up to 150 kHz and draws a typically current of 1.3 mA, making it capable of being powered by many low-power batteries.

The DS1708SEPA+ operates in low-voltage and low-power systems, making it well-suited to be implemented in applications such as consumer electronics and portable medical equipment. The device\'s integrated temperature sensor allows it to detect thermal events, and its low DOWNV provides increased precision compared to the more common 5V and 10V voltage thresholds of other supervisory ICs. The device also comes with a choice of signal output types, which can be configured in the form of an open collector, totem pole, push/pull, or pulse/reverse/toggle, or in the form of an analog voltage or current.

The DS1708SEPA+ is a highly flexible and reliable low-power supervisor, capable of operating in a variety of portable applications. Its accurate undervoltage and temperature detection abilities make it well-suited for applications such as consumer electronics, portable medical equipment, and battery-backed systems. And its low-current operation and compact form factor enables it to be integrated into a wide range of designs.
