摘要： A supply voltage level detection circuit makes use of an additional supply already provided for power. A voltage detection circuit defines a first threshold, and a differencing circuit defines a second threshold. The output state of the differencing circuit is saved in a latch. The latch may be cross coupled gates of cross coupled inverters. When inverters are used, the differencing circuit output contends with the internal latch drive when setting or resetting the latch. The design allows the differencing circuit to overcome the inverter's internal drives to change the logic state of the latch.

摘要： An apparatus comprises an integrated circuit (IC) comprising an external IC connection, an IC substrate connection, a voltage clamp circuit and an under voltage circuit. The voltage of the IC substrate connection is set to a first voltage when a voltage of the external connection of the IC is within a normal operating voltage range. The voltage clamp circuit is configured to clamp the voltage supply of one or more circuits internal to the IC to within a normal operating voltage range when the voltage of the external IC connection exceeds the normal operating voltage range. The under voltage circuit is communicatively coupled to the clamp circuit and configured to set the voltage of the substrate to a second voltage when the voltage at the external IC connection of the IC is less than zero volts.

摘要： This document discusses, among other things, systems and methods to provide an internal supply rail with over voltage protection using a host power source, an external power source, and a switch configured to receive indications of host and external power source validity. In an example, the switch can be configured to provide the internal supply rail using the host power source when the indication of host power source validity indicates a valid host power source and the external power source when the indication of host power source validity indicates an invalid host power source and the indication of external power source validity indicates a valid external power source.

摘要： This document discusses, among other things, apparatus and methods configured to accurately identify accessories coupled to mobile electronic devices over a wide range of temperature, In an example, an apparatus can include a reference voltage generator configured to provide a reference voltage, a comparator configured to compare the reference voltage to a voltage across an accessory-resistor, a current supply configured to be coupled to the accessory resistor and to provide the voltage to the comparator using the accessory resistor. The current supply can include a first sense resistor having a first temperature dependency and a second sense resistor having a second temperature dependency. In an example, the second temperature dependency can be configured to compensate for at least a portion of the first temperature dependency. In an example, at least one of the first or second temperature dependencies can be configured to control a temperature dependency of the apparatus.
