oscillate at the preheat frequency with 50% duty
cycle and with a dead-time which is set by the
value of the external timing capacitor, CT, and
internal deadtime resistor, RDT. Pin CPH is
disconnected from COM and an internal 3 μ A
current source (Figure 3)
V BUS (+)
VCC is the dead-time (both off) of the output
gate drivers, HO and LO. The selected value of
CT together with RDT therefore program the
desired dead-time (see Design Equations, page
26, Equations 1 and 2). Once CT discharges
below 1/3 VCC, MOSFET S3 is turned off,
disconnecting RDT from COM, and MOSFET
S1 is turned on, connecting RT and RPH again
to VCC. The frequency remains at the preheat

preheat mode, the over-current protection
together with the fault counter are enabled. The
