SLVSGZ1A May 2024 – July 2024 DRV8161 , DRV8162
ADVANCE INFORMATION
The table lists the recommended values of the external components for the gate driver.
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. |
CGVDD_LS | GVDD_LS | GND | 1-μF, VGVDD-rated capacitor |
CVDRAIN | VDRAIN | GND | 0.1-μF, VVDRAIN-rated capacitor |
