8.3.3.1 Bootstrap Charging Methods

The TPS7H6101 provides the user several options for charging the bootstrap capacitor. This flexibility allows for operation with a wide range of PWM controllers and also allows the user to select an option with trade-offs that are most desirable for the specific application. In both instances, a bootstrap resistor is recommended to limit the bootstrap current during initial startup. The bootstrap resistor and capacitor need to be chosen such that sufficient time is allowed for the recharge of the capacitor for the specific application.
