... MHz. An integrated 30 V bootstrap Schottky diode is used to charge the external bootstrap capacitor. An internal watchdog circuit prevents excessive shoot-through currents and protects the external MOSFET switches. The ZL1505 is specified over a wide -40 °C to 125 °C junction temperature range and is available in an exposed pad DFN-10 package. VDD PWMH ...
