Functional Description
SP600
The SP600 provides a flexible, digitally controlled power function which is intended to be used as PWM drivers of N-Channel MOSFETs and/or IGBTs for up to 240VAC line rectified totem-pole applications. The CMOS driveable inputs are filtered and captured by the control logic to deter­mine the output state. The logic includes fixed timing to pro­hibit simultaneous conduction of the external power switches and, thru the V
sense detector, verifies the output volt-
OUT
age state is in agreement with the controlled inputs. The >11V
floating power supply required to drivethe upper rail
DC
external power device is created and managed by the HVIC through C supply each time V
and DF. This capacitor is refreshed from the V
F
goes low. If the upper channel is
OUT
DD
commanded on for a long period of time, the bootstrap capacitor CF is automatically refreshed by bringing V
OUT
low. This is accomplished by turning off the upper rail MOS­FET/IGBT, momentarily turning on the lower rail output device, followed by returning control back to the upper switch. Otherwise, C
would gradually deplete its charge
F
allowing the upper switch to come out of saturation. The upper and lower gate drivers allow for controlled charge and discharge rates as well as facilitate the use of nearly lossless current sensing power MOS devices. The over current trip level can be boosted 30% on a pulse by pulse basis by logic level ‘1’ applied to I
TRIPSELECT
.AFAULT output signal is
generated when any of the following occurs:
V bias is low Over current is detected V phase doesn’t agree with the input signal
Reset of
FAULT is provided by externally removing power or by holding both TOP and BOT inputs low for the required reset time (trt
MAX
).
Each application can be individually optimized by the selec­tion of external components tailored to ensure proper overall system operation including:
Determining the ratings and sizing of MOSFETs and IGBTs, mixed or matched, as well as flyback diodes (FBD).
The selection of separate gate charge (R (R

the capacitor, the amount of charge transfer required by the load, and cost. Due to automatic refresh the capacitor is replenished every 350µs TYP (or even sooner if input com­mands the TOP to switch at a faster repetition rate).
