TL7702 آیسی ناظر ولتاژ

تخفیف ویژه

After power-on a digital system must be forced into a definite initial state. For microcomputers and microprocessors a Reset input is provided to which, in simple applications, an R/C network is connected. After power-on, this circuitry maintains the logic level at this input high (or low), until the supply voltage has reached its nominal value, and the internal logic of the microcomputer has executed the Reset. However, this simple circuit does not work well under all conditions, or during short drops of the supply voltage. This applications report describes the operation and the application of the supply voltage supervisor circuits series TL77xx, which has been specially designed to solve these applications problems
