In a previous figure (Part 1) of an H-Bridge circuit (reproduced below), the current of T2 and T4 is sensed via the sense switches T2S and T4S and compared with a threshold via comparators Comp3 and ...

The FET-sense current detection guarantees high accuracy in over-current and short-circuit detection, making it an indispensable tool for any battery-powered device. The NB7142 and NB7143 series are ...

1. The over-current detection scheme via an op amp and comparator is the most complex solution and offers the lowest accuracy, but in many cases it also will be the lowest-cost alternative.

Features - No need for a current sense resistor - No need for an external capacitor for the charge pump circuit - Low power consumption in sleep mode: I M1 =1μA (max) @sleep mode Main Specifications ...

The shunt + iso-amp current sensing devices on the output phases and DC bus provide fault detection in addition to current measurement. Typical IGBT short-circuit survival times are rated up to 10 ...

Peak current is up to 3 times the primary nominal current reaching 450 A pk with the 150 ARMS. An over-current detection output with a threshold set at 1.93 x IPN is also offered as an option on an ...
