Powering the system is required by many applications while charging the battery simultaneously. Interaction between the system and charger may result in a false charge stoppage caused by the safety timer when the system is directly connected to the battery-charge output. The circuit diagram below shows a typical application circuit that removes such issues. This circuit has two independent power […]
Read moreDC/DC step-up converter is applicable on battery-powered equipment. DC/DC step-up converter can be used to generate supply voltages for internal circuits that require higher voltages than the available battery voltage. There’s two kind of converters, inductive and capacitive. Inductive step-up converters have a high efficiency over the entire input voltage range. Capacitive converters-i.e., charge pumps give us a high efficiency […]

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 […]
