Abstract: An isolation structure is provided to give improved protection from below ground current injection. A first epitaxial region is provided between a power field effect device and nearby control circuitry. The first epitaxial region is tied to the substrate, and the ties are located between the first epitaxial region and the power field effect device. On the opposite side of the power device, preferably adjacent an edge of the integrated circuit chip, a second epitaxial region is formed. This epitaxial region is connected to the first epitaxial region, preferably by a metal interconnect line. A second set of substrate contacts is located between the power device and the second epitaxial region, and is tied to ground. The second epitaxial region encourages injection of current at a location spaced away from the control circuitry.

The apparatus also includes a replica module having a second leg, where the first and second legs have a common structure. The apparatus further includes a feedback loop configured to cause an output voltage across terminals of the replica module to at least substantially equal an input voltage across terminals of the sense module based on sense currents in the first and second legs. At least one cascode stage coupled to the sense module can be configured to reduce a voltage at which one or more signals from the sense module are referenced.

Abstract: A control circuit for providing a stable, adjustable, time constant for use as a master time constant is presented. Used as a master time-constant circuit, this control circuit can ensure multiple slave circuits are precisely calibrated. The circuit includes a charging section that receives a series of calibrating pulses. The reference cell's voltage is compared to a reference voltage equal of Vcc/e. If the cell's voltage is below the reference voltage, a current source charges a capacitor, lowering the resistance of the transistor in the cell to correct the time circuit inaccuracy. Conversely, if the cell's voltage is above the reference voltage, a current sink discharges the capacitor, raising the transistor's resistance. This also corrects the time circuit inaccuracy. Thus, this circuit includes a method to correct time-constants which are too large or too small. This circuit is used in various applications where extreme accuracy and precision is needed, such as media drive read/write heads.

Abstract: A motor drive control circuit for operation in both linear and PWM modes includes a switchably connected compensation network. The compensation network has a capacitor that provides control loop compensation. To avoid transient effects during the settling time upon transitions from one mode to the other, the switch connecting the compensation network in the circuit is closed only during linear operation and not during PWM mode operation. When the switch is open, the capacitor holds a previously attained potential that is reapplied to the circuit when the switch is again closed.

Abstract: A switch circuit for a charge pump circuit is disclosed. The switch circuit has a first transistor for conducting current and is controlled by a second, third, and fourth transistor. The second transistor protects the first transistor for excessive gate-to-drain voltage. The third transistor receives the signal for switching the switch circuit and also serves as a cascoding transistor for protecting the fourth transistor from excessive gate-to-drain voltage. Consequently, the switch circuit can withstand high gate-to-drain voltages and has increased reliability. The switch also has a turn-off circuit to facilitate the depletion of charge on the control element of the first transistor. The switch circuit also has a zener diode to insure that excessive voltage is not applied across the gate-to drain of the first transistor.
