Power Transistor Driver Circuit With Current Sensing And Current Overprotection And Method For Protecting Power Transistor From Overcurrent
US Patent:
5325258, Jun 28, 1994
Filed:
Aug 26, 1992
Appl. No.:
7/936028
Inventors:
Chris Choi - Redondo Beach CA
David Tam - Redondo Beach CA
David Tam - Redondo Beach CA
Assignee:
International Rectifier Corporation - El Segundo CA
International Classification:
H02H 326
G05F 1573
G05F 1573
US Classification:
361 87
Abstract:
A circuit and method for driving a power transistor device. The circuit for driving a power transistor device has a driver having an input and an output, the output coupled to a control input of the power transistor device and the input coupled to a primary control voltage source for driving the power transistor device. A current sensing device is coupled to the power transistor device for providing a signal proportional to the current in the power transistor device. An amplifier is coupled to the current sensing device for providing a substantially linear control signal proportional to the current in the power transistor device, the linear control signal being provided to the input of the driver as a secondary drive signal for driving the power transistor device when a current level in the power transistor device greater than a threshold level is detected. A detector is provided for detecting when the current in the power transistor device is greater than the threshold level. The detector is coupled to the current sensing device and to a reference level source, and provides an overcurrent signal to the driver for switching the driver from being driven by the primary control voltage source to the secondary drive signal.
