Abstract: A die is mounted in an integrated circuit package. The die includes a balun circuit and an electrostatic discharge (ESD) circuit coupled to a ground of the integrated circuit die. The package has a first output pin coupled to a first terminal of the balun and has a second output pin coupled to a second terminal of the balun through first and second bond wires. The second output pin is connected to board ground. A third bond wire is disposed between the second package terminal and the ESD circuit to provide a safe discharge path through the third bond wire for ESD events affecting the first and second output terminals. Thus, a charge that builds up involving one of the output terminals coupled to the balun can be safely dissipated.

Abstract: An apparatus for communicating using an isolation channel includes a transmitter circuit having a first terminal configured to communicate a first signal. The first signal oscillates in response to a data signal having a first signal level and is constant in response to the data signal having a second signal level. The transmitter circuit includes a second terminal configured to communicate that oscillates in response to the data signal having the second signal level and is constant in response to the data signal having the first signal level. The apparatus may include a receiver circuit configured to generate a recovered data signal having a first transition in a first direction between first and second levels based on an edge of a first received signal and having a second transition in a second direction between the first and second levels based on an edge of a second received signal.

Abstract: The charge drawn from a battery during each switching event (pulse) of a pulse frequency modulated DC-DC converter is determined during a calibration period. based on differences in pulse rate with different current loading. Another approach calibration approach determines charge drawn from the battery by measuring voltage across a sense resistor while measuring the total pulse rate and while adding sufficient load current to ensure that the voltage is much larger than the residual offset of the measurement system. During operation, the system counts number of pulses are counted and the total charge drawn from the battery is determined based, at least in part, on the charge transferred per pulse during calibration, the operational mode, the battery voltage during calibration and operationally and the output voltage. Based on the total charge drawn and temperature (for temperature dependent battery types), the battery state of charge is estimated.

Abstract: Common mode transient immunity for an isolation system is improved by using a common transient suppression circuit coupled to a receive circuit to suppress transients in signals received by the receive circuit that were transmitted from a transmit side of the isolation barrier using optical, magnetic, inductive, or other mechanisms.

Abstract: A calibration current load is selectively coupled to an output of a pulse frequency modulated (PFM) DC-DC converter during a calibration operation to increase charge supplied from a battery supplying an input voltage to the converter. A voltage across a sense resistor in series with the battery is integrated during a measurement interval while the calibration current load is coupled to the output. A charge drawn per pulse from the battery is determined based on the sense resistor, the integrated voltage and the number of pulses during the measurement interval. Alternatively, a first PFM frequency is determined with a first calibration current load coupled to the converter output. A second PFM frequency is determined with a second calibration current load. The charge drawn per pulse from the battery is determined based on the first and second PFM frequencies and the first and second calibration current loads.
