Control Of Cooling Fan By Using Power Supply Current
US Patent:
5598314, Jan 28, 1997
Filed:
Nov 2, 1993
Appl. No.:
8/146545
Inventors:
Steven G. Hall - Fort Collins CO
Assignee:
Hewlett-Packard Company - Palo Alto CA
International Classification:
H02H 300
US Classification:
361 93
Abstract:
A control system for a cooling fan in an electronic system. Power consumption (and therefore heat) is sensed by sensing power supply current. When power supply current exceeds a threshold value, the cooling fan is turned ON. In a specific embodiment, a small (low-resistance) series resistor is placed in the regulated output path of a power supply. Power supply current is measured by measuring the voltage drop across the resistor.

Assignee:
Hewlett-Packard Company - Palo Alto CA
International Classification:
H03K 1704
US Classification:
327108
Abstract:
A digital line driver circuit with active pull-down, high transient pull-up current, and limited steady-state pull-up current. Steady-state pull-up current is provided through a pull-up resistor. Transient pull-up current is provided by a capacitively coupled active pull-up circuit.
