Patent
H-bridge drive utilizing a pair of high and low side MOSFET's in a common insulation housing
TL;DR: In this article, a fully protected H-bridge for a d-c motor consists of two high side MOSFETs and a control and logic IC on a first conductive heat sink all within a first package and two discrete low-side MOSFLETs.
Patent
Anti-pinch window drive circuit
TL;DR: In this article, an antipinch circuit was proposed to prevent the motor driven closure of an automotive window if a soft obstacle is compressed between the window and the top of the door frame, and the window is opened in response to the sensing of the obstacle.
Patent
High side power switch with charge pump and bootstrap capacitor
TL;DR: In this paper, a power switching circuit (10) comprising a power semiconductor switching device (Q1), a charge pump circuit (CHP) having a control input to control whether it is on or off and a charge pumps output, the charge pump output being coupled to a control terminal of the PSS device, a bootstrap power supply for supplying power to driver circuitry for the power SINR switching device, the bootstrap capacitor (CBS) coupled with a charging current source, and the bootstrapping power supply providing power to the driver circuitry when the PSIN
Patent
Buck converter with improved filter design
TL;DR: A buck converter for use in controlling a motor in accordance with the embodiment of the present invention includes a power input operable for connection to a DC power supply, a switch for selectively connecting the motor to the power supply and a pulse width modulation controller operable to provide a pulsewidth modulation signal to the switch as discussed by the authors.
Patent
Method for operating an H-bridge drive utilizing a pair of high and low side MOSFETS
TL;DR: In this paper, a fully protected H-bridge for a d-c motor consists of two high side MOSFETs and a control and logic IC on a first conductive heat sink all within a first package and two discrete low-side MOSFLETs.
