... ESD Protection 1. Description The ATA6025 is a monolithic circuit based on Atmel’s smart power BCD60-III technol- ogy universal IC for monitoring basic functions of an automotive application possible to monitor the battery voltage (VKL15) and an external 5V voltage regula- tor. With the independent watchdog the correct function of a microcontroller can be observed ...

... The pin CLK is normally open or connected to GND. If the internal clock frequency checked, the CLK pin has to be connected with an external resistor Rex = supply. The measured value is the clock frequency divided by four. ATA6025 4 = 400 ms to low (see Figure 8-3 on page ...
