Overcurrent Monitor Operates up to 26V

资料介绍
Abstract: Using a current-sense amplifier, a high-side MOSFET driver, and a latching voltage monitor a circuit can be easily constructed that protects from overcurrent conditions and operates at voltages as high as 26V.

APPLICATION NOTE 240
Overcurrent Monitor Operates up to 26V

Abstract: Using a current-sense amplifier, a high-side MOSFET driver, and a latching voltage monitor a circuit can be easily constructed that protects
from overcurrent conditions and operates at voltages as high as 26V.


Widespread use of the Universal Serial Bus (USB) has led to a selection of overcurrent-protection circuits for supply rails in the +2.7V to +5.5V range,
but few products are available for voltages above that range. The circuit breaker in Figure 1 operates on supply voltages ……
