Patent number: 9268350Abstract: A voltage feedback loop employed with a power distribution switch rapidly responds to a predetermined drop in output voltage to increase the resistance of the switch for a predetermined time. After this predetermined time, a current feedback loop controls the resistance until the output voltage recovers, while also isolating the voltage feedback loop from the switch.Type: GrantFiled: August 8, 2013Date of Patent: February 23, 2016Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: H.

Patent number: 8040652Abstract: Programmable power distribution switches with two-level current sensing are disclosed. In a particular example, a power distribution switch includes a programmable output device having a resistance based on a programmed maximum output current and generates an output voltage based on the resistance and a load current. The example power distribution switch also includes a reference voltage generator that is configured to generate a reference voltage corresponding to the output voltage when the load current is substantially equal to the programmed maximum output current. A current limiter is also included to reduce the load current in response to a comparison of the output voltage and the reference voltage, when the comparison is indicative of the load current exceeding the programmed maximum output current.Type: GrantFiled: August 26, 2008Date of Patent: October 18, 2011Assignee: Texas Instruments IncorporatedInventors: H. Pooya Forghani-zadeh, Thomas A. Schmidt
