8.2.3 External Components

The table lists the recommended values of the external components for the gate driver.

Table 8-1 DRV816x External Components
COMPONENTS PIN 1 PIN 2 RECOMMENDED
CBST BST SH 1.0-μF, VBST-SH-rated capacitor between BST and SH depending on the total gate charge of external MOSFET Qg. CBST > 20 X Qg / (VGH-VSH). The maximum CBST is 2.2-μF,
CGVDD GVDD GND 10-μF, VGVDD-rated capacitor. This capacitor can be shared with the other two DRV816x devices in 3-phase power stage design if the capacitor is placed sufficiently close to all the three devices. The voltage drop due to bootstrap operation at power up and during PWM switching must be reviewed by users.
