This is a circuit of discrete overvoltage protector for automotive application. There are two basic thing that must be done by protection circuit. They are prevent voltages greater than the maximum allowable from being applied to the IC pins and the protection circuit not to intrude on the normal function of the circuit. Beside that, it must be fast enough […]

This a high-side current amplifier circuit breaker. The circuit-breaker application is possible for that device because  the latching-comparator output (COUT1) on the MAX4373, a high-side current-sense amplifier with reference and comparator. Here is the circuit : This circuit uses MAX4373FESA as a circuit-breaker threshold of 900mA, because its gain from sense resistor to output is 50V/V. Thus, 900mA through the […]
