7.1 Functional Block Diagram
7.2 Feature Description
7.2.1 Powering CSD95375Q4M And Gate Drivers
An external VDD voltage is required to supply the integrated gate driver IC and provide the necessary gate drive
power for the MOSFETS. A 1 µF 10 V X5R or higher ceramic capacitor is recommended to bypass VDD pin to
PGND. A bootstrap circuit to provide gate drive power for the Control FET is also included. The bootstrap supply
to drive the Control FET is generated by connecting a 100 nF 16 V X5R ceramic capacitor between BOOT and
BOOT_R pins. An optional RBOOT resistor can be used to slow down the turn on speed of the Control FET and
reduce voltage spikes on the VSW node. A typical 1 Ω to 4.7 Ω value is a compromise between switching loss
and VSW spike amplitude.
7.3 Undervoltage Lockout Protection (UVLO)
The undervoltage lockout (UVLO) comparator evaluates the VDD voltage level. As VVDD rises, both the Control
FET and Sync FET gates hold actively low at all times until VVDD reaches the higher UVLO threshold (VUVLO_H).,
Then the driver becomes operational and responds to PWM and SKIP# commands. If VDD falls below the lower
UVLO threshold (VUVLO_L = VUVLO_H – Hysteresis), the device disables the driver and drives the outputs of the
Control FET and Sync FET gates actively low. Figure 12 shows this function.
CAUTION
Do not start the driver in the very low power mode (SKIP# = Tri-state).
