Circuit description
4.1
Power stages and charge pump
The L6226Q integrates two independent power MOS full bridges. Each power MOS has an
RDS(on) = 0.73 Ω (typical value @ 25 °C), with intrinsic fast freewheeling diode. Cross
conduction protection is achieved using a dead time (td = 1
μs typical) between the switch
off and switch on of two power MOS in one leg of a bridge.
Using N-channel power MOS for the upper transistors in the bridge requires a gate drive
voltage above the power supply voltage. The bootstrapped (VBOOT) supply is obtained
through an internal oscillator and few external components to realize a charge pump circuit
as shown in Figure 5. The oscillator output (VCP) is a square wave at 600 kHz (typical) with
10 V amplitude. Recommended values/part numbers for the charge pump circuit are shown
Figure 5.
