Publication number: 20060238154Abstract: A control circuit is described in which a single input terminal receives digital control signals and analog control signals. In accordance with the principles of the invention, the control circuit includes an automatic power down circuit to place the control circuit into a low power draw or “sleep” mode whenever predetermined conditions are present. The automatic power down circuit monitors the single input terminal and when no demand for motor operation occurs for a predetermined period of time, the automatic power down circuit operates to place the control circuit into the low power draw mode.Type: ApplicationFiled: April 27, 2006Publication date: October 26, 2006Applicant: ANDIGILOG, INC.Inventors: Robert Brannen, Jade Alberkrack

Publication number: 20060208821Abstract: A control circuit is described in which a single input terminal receives digital control signals and analog control signals. A circuit coupled to the single input provides a first output to indicate that a signal at said single input terminal is a digital signal and a second output indicates that a signal at said single input terminal is an analog signal.Type: ApplicationFiled: January 31, 2006Publication date: September 21, 2006Applicant: ANDIGILOG, INC.Inventor: Jade Alberkrack

Patent number: 6137696Abstract: A switching power supply (10) uses a switching regulator (18) that is capable of operating in a dual mode with either primary side regulation or secondary side regulation. The primary and secondary side regulation schemes generate opposite phase feedback signals. The switching regulator has first (56, 62) and second (70, 74) detectors on the feedback input which detect when the feedback signal is less than a first value and also detect when the feedback signal is greater than a second value. By monitoring either case, the switching regulator can enable and disable a gate drive signal in response to opposite phases of the feedback signal and thereby regulate the switching power supply.Type: GrantFiled: April 12, 1999Date of Patent: October 24, 2000Assignee: Semicondutor Components Industries, LLCInventors: Jefferson W.

Patent number: 5920181Abstract: A battery protection system (20) controls a process for charging a battery pack (15). A hysteresis comparator (54) senses a charging current flowing through the battery pack (15) and switches off a charging switch (31) to interrupt the charging current when the charging current reaches an upper limit. A transient current is then generated by an inductor (34). The hysteresis comparator (54) senses the transient current flowing through the battery pack (15) and switches on the charging switch (31) to regenerate the charging current when the transient current decreases substantially to zero. Periodically, a battery monitoring circuit (40) switches off the charging switch (31) and measures an open circuit voltage across each battery cell in the battery pack (15). In response to the open circuit voltage of a battery cell reaching a fully charged voltage, the battery monitoring circuit (40) switches off the charging switch (31) to terminate the charging process.Type: GrantFiled: June 24, 1998Date of Patent: July 6, 1999Assignee: MotorolaInventors: Jade Alberkrack, Troy L.

Patent number: RE45862Abstract: A single input pin (48) provides multi-functional features for programming a power supply (10). By connecting the appropriate interface circuit (92, 100, or 112) to the single input pin (48), the power supply (10) is programmed for specific behaviors during power up and toggling of an on/off switch (96, 108). In one mode of operation a light emitting diode (106) in the interface circuit (100) is optically coupled to a microprocessor for signaling the closure of the on/off switch (108), allowing the microprocessor to control the power supply (10) through an opto-coupler (102). In another mode of operation, the single on/off switch (96) controls the power supply (10). In yet another mode of operation, Zener diode (118) in the interface circuit (112) controls the power supply (10) during brown-out and black-out conditions.Type: GrantFiled: October 28, 2010Date of Patent: January 19, 2016Assignee: Semiconductor Components Industries, LLCInventors: Jefferson W.
