A high-speed, current source/sink utilizes a current mode operational amplifier 210 to drive a power MOSFET 212 without ringing or instability. A charge equivalent to a desired current output is stored on a charge storage means Cp and a switch 202 is enabled e.g. by an optical signal, so...
The intelligent driving algorithm concept proposes a realization of power MOSFET gate driving with controlled source/sink current of the power MOSFET driver circuit. Such approach enables higher control of the power MOSFET operation behavior,... Jurij Podraj,J Trontelj - 《Facta Universitatis》 被引...
This circuit implements a differential load measurement for an ADC using twin unidirectional sense measurements. Each LTC6101 performs high side sensing that rapidly responds to fault conditions, including load shorts and MOSFET failures. Hardware local to the switch module (not shown in the diagram) ...
In NXP reference design MotorGD DevKit the DC current shunt is used to protect against overcurrent in HW using the MOSFET pre-driver built in circuit and R72 potentiate to set the protection level. In general for over-current you need to act very quickly. Hope this helps! Daniel 1 Kudo ...
To understand the key trade-offs, options, and challenges faced by system designers when choosing the most accurate, cost-effective current sensor for a circuit board, we take a close look at current sensing in LDMOS bias current monitoring in cellular base station power amplifiers and other...
