PROTECTION AND DIAGNOSIS FEATURES
Figure 20. Power Dissipation Profile of Application Not Using Charge Pump
Reference application with:
• Output FET gate charge: 240 nC @ 10V
• PWM Frequency: 20kHz
• Switching Single Phase
• No connections to PUMP or VPUMP
• VPWR connected to Vbat
If VPWR is supplied by a separate pre-regulator, the power dissipation profile will be nearly flat at the value of the pre-regulator
voltage for all Vbat voltages.
