The Figure 8 represents a simplified circuitry of the high side gate driver.
Figure 8. High Side Gate Driver
The transistors Tosc1 and Tosc2 are the oscillator switching MOSFETs. When Tosc1 is on, the oscillator is at low level. When
Tosc2 is on, the oscillator is at high level. The high side MOSFET predriver is composed of two transistors T1 and T2. When T1 is on
the HS MOSFET is turn on, when T2 is on the HS MOSFET is off. The capacitor Ccp_out provides peak current to the HS MOSFET
through T1 during turn on (3) as shown in figure 11.
Ccp
Ccp choice depends on Power MOSFET characteristics and the working switching frequency. The following diagrams show the
influence of Ccp value on Vcp_out average voltage level. The diagrams are given at two different frequencies for two power MOSFETs
(MTP60N06HD and MPT36N06V).
