摘要： A battery protection circuit includes a moisture detection circuit, a temperature sensing circuit, and a high-temperature battery discharge circuit. The moisture detection circuit includes a pair of conductive traces closely spaced on a substrate such that a resistive path is formed between the traces when moisture forms on the substrate. The traces are connected between the positive battery terminal and a pull-down current source. When moisture forms on the substrate, pull-up current flows between the traces, and a resulting voltage change on one of the traces is detected by circuit element such as a logic inverter. The temperature sensing circuit includes a voltage reference circuit that generates a proportional-to-temperature voltage and temperature-independent voltage reference signals corresponding to various predetermined temperatures. A measuring circuit operates during a sampling interval to compare each temperature-dependent voltage to the proportional-to-temperature voltage and to store the result of each comparison until a subsequent temperature sampling interval. The measuring circuit includes multiplexing circuitry used to sequentially select each temperature-dependent voltage during a sampling interval. The high-temperature discharge circuit connects a discharge load across the battery when the voltage of the battery is above a high voltage threshold and the temperature of the battery is above the high temperature threshold. When no external charger is active, the discharge current flowing through this load works to reduce battery voltage. helping to prolong battery life.

摘要： A battery protection circuit includes back-to-back connected metal-oxide-semiconductor field-effect transistors (MOSFETs). Detection circuitry detects whether the battery is in a normal charge condition, an overcharged condition, or an over-discharged condition, and for the overcharged and over-discharged conditions the circuitry asserts a corresponding enable signal. For each MOSFET, a corresponding gate voltage regulating circuit controls the gate voltage such that (i) when the corresponding enable signal is de-asserted, the gate voltage is sufficient to enable the MOSFET to strongly conduct current in either direction, and (ii) when the corresponding enable signal is asserted, the gate voltage is a function of the polarity of drain-to-source voltage of the MOSFET. For each MOSFET, the corresponding gate voltage regulating circuit prevents the MOSFET from conducting when the drain-to-source voltage has an undesired polarity, and allows the MOSFET to conduct when the drain-to-source voltage has a desired polarity. One MOSFET prevents the flow of charge current, and the other prevents the flow of discharge current. When either MOSFET is conducting, its drain-to-source voltage is prevented from achieving a value sufficient to forward bias a parasitic diode associated with the source and drain terminals of the MOSFET. Current of correct polarity flows through the source-to-drain channel of a MOSFET rather than through the parasitic diode during the overcharged and over-discharged conditions.

摘要： An apparatus to provide overvoltage protection is shown. The apparatus comprises a boost converter (having an output node, a sensing network, and an impedance network) and a zener diode. The zener diode is coupled to the output node and to the sensing network. The breakdown value of the zener diode is selected to be greater than a desired voltage drop across a load when the load is coupled to the output node, and the zener diode creates an overcurrent fault in the boost converter when the voltage at the output node is greater than its breakdown value.

摘要： Various embodiments of the present invention provide rectifier controllers, power supplies and methods for operating such. As one example, a rectifier controller circuit is disclosed that includes a transistor, a phase locked loop circuit, a period counter and a combinational logic circuit. One leg of the transistor is electrically coupled to a switch node of a power supply, and is in parallel to a diode of the power supply. The phase locked loop circuit receives a signal representing a voltage at the switch node, and is operable to synchronize to a period of the signal representing the voltage at the switch node. The period counter divides the period of the signal representing the voltage at the switch node into segments. The combinational logic circuit is operable to turn the transistor on an assertion delay period after a first transition of the signal representing the voltage at the switch node, and to turn the transistor off before a second transition of the signal representing the voltage at the switch node based on the period counter.

摘要： A signal processor operates on a microprocessor or state machine based system to ensure that the central processing unit (CPU) and pulse generator (PG) have finished their instructions before allowing a new transition on the system master clock. The CPU and PG contain circuitry which allows them to indicate when they are busy. These signals are fed to the signal processor to indicate when the CPU and PG are ready to start another instruction. The signal processor functions to prevent a noise glitch on the system clock from causing another operation to start before the one in process has finished. The output of the signal processor becomes the master clock signal used by the system.
