Patent number: 8604763Abstract: A sensing circuit senses a load current to generate a sensed signal. A comparator's output is set to a first value if the sensed signal is equal to or greater than a reference signal, and to a second value if the sensed signal is smaller than the reference signal. A one-shot timer generates a logic signal that transitions from a first state to a second state in response to a first occurrence of the first value of the comparator's output, or optionally in response to each subsequent occurrence of the first value of the comparator's output if the one-shot timer is rearmed. A selector sets a first limit for the current delivered to the load in response to the first state of the logic signal, and a second limit for the current delivered to the load in response to the second state of the logic signal.Type: GrantFiled: August 31, 2010Date of Patent: December 10, 2013Assignee: Decicon, Inc.Inventor: Hakan Ates Gurcan

Patent number: 8552791Abstract: Under-voltage, over-voltage, and temperature detectors disposed in a switching circuit are turned on periodically and in response to an oscillating signal having a low duty cycle. Accordingly, because the voltage and temperature detectors remain off for long durations, their operating currents, and thus the operating current of the switching circuit is substantially reduced. The switching circuit has a current limiting function which is disabled when the switch current is below a threshold value, thereby further decreasing the current consumption of the switching circuit at low switch current levels.Type: GrantFiled: September 23, 2009Date of Patent: October 8, 2013Assignee: Decicon, Inc.Inventors: Volkan Sahin, Murat Okyar, Hakan Ates Gurcan

Patent number: 8294441Abstract: A voltage regulator includes first and second closed-loop amplifiers and a N-type transistor. The first amplifier receives a first reference voltage and a feedback voltage. The second amplifier is responsive to the first amplifier and to the regulated output voltage of the regulator. Both amplifiers are biased by a biasing voltage. The second amplifier has a bandwidth greater than the bandwidth of the first amplifier and a gain smaller that the gain of the first amplifier. The N-type transistor has a first terminal responsive to the output of the second amplifier, a second terminal that receives the input voltage being regulated, and a third terminal that supplies the regulated output voltage. The feedback voltage is generating by dividing the regulated output voltage. An optional fixed or dynamically biased current source biases the first terminal of the N-type transistor. The voltage regulator optionally includes an overshoot correction circuit.Type: GrantFiled: November 13, 2007Date of Patent: October 23, 2012Assignee: Decicon, Inc.Inventors: Hakan Ates Gurcan, Murat Mehmet Okyar

Patent number: 7012450Abstract: A low-voltage differential signal driver includes, in part, a current sourcing circuit, a current steering circuit, and a current sinking circuit. The current steering circuit steers the current generated by the current sourcing circuit in one of first and second directions to generate a positive or a negative differential output voltage.

A first voltage regulating circuit receives a first reference voltage and regulates the voltage of a node common to both the current steering circuit and the current sinking circuit. A second voltage regulating circuit receives a first voltage supply to regulate the voltage signal generated by the voltage dividing circuit. To track the on-resistance of the transistors disposed in the current steering circuitry, a replicating circuit receives the first voltage supply and generates the first reference voltage.Type: GrantFiled: December 15, 2003Date of Patent: March 14, 2006Assignee: Decicon, Inc.Inventors: Hakan Oner, Hakan Ates Gurcan, Ismail Okter
