TPV708中文资料Low-Voltage Supervisory Circuits with Power-Fail Detector数据手册3PEAK规格书

描述 Description

The TPV708 is a family of supervisory circuits to monitor power supply voltage levels and provides a power-on reset signal.

A reset signal can be asserted by an external manual reset input.

In addition, there is a power-fail detector with a 1.25-V threshold, which can be used to monitor an additional power supply.

The reset periods are fixed at 200 ms (typical). The TPV708 is available in an 8-pin SOP package and typically consumes only 4 μA, which is suitable for low-power and portable applications.
