Web28 de jul. de 2024 · Unfortunately, modifying/resetting the ports on a defined circuit object is currently not possible. Once a circuit object is created, and setports/setterminals is used, the circuit is defined and cannot be changed. Indeed, the only way to go about it would be to just clear the circuit object and make a new one with the desired parameters.

Web28 de nov. de 2024 · \$\begingroup\$ UVLO has absolutely nothing to do with the bootstrap voltage, it detects the VCC voltage to prevent driving under conditions where the low side is not driven completely. This is because the failure to provide a low on the external FETs will result in no charge on the bootstrap caps. The circuit would still try to work, but the … In the field of electronics, a technique where part of the output of a system is used at startup can be described as bootstrapping. A bootstrap circuit is one where part of the output of an amplifier stage is applied to the input, so as to alter the input impedance of the amplifier. When applied deliberately, the intention is usually to increase rather than decrease the impedance.
