MC33157/D
The MC33157 includes the oscillator circuit and two output
channels to control a half–bridge power stage.
One of the channels is ground–referenced. The second one is
floating to provide a bootstrap operation for the high side switch.
Dedicated Driver for Industrial Linear Tubes
Main oscillator is current controlled, making it easy to set up by a
single external resistor. On top of that, such a feature is useful to
implement a dimming function by frequency shift.
Filament pre–heating time control built–in.
The strike sequence is controllable by external passive components,
the resonnant frequency being independently adjustable. This
frequency can be made different from the pre–heating and the steady
state values. A frequency sweep between two defined values makes
this IC suitable for any series resonnant topologies.
Dedicated internal comparator provides an easy lamp strike detection
implementation.
Digital RESET pin provides a fast reset of the system (less than 10
μ
s).
Both output MOSFET are set to “OFF” state when RESET is zero.
Adjustable dead time makes the product suitable for any snubber
capacitor and size of MOSFET used as power switches.
Designed to be used with standard setting capacitors
≤
470nF.
A voltage reference, derived from the internal bandgap, is provided
for external usage. This voltage is 100% trimmed at probe level
yielding a 2% tolerance over the temperature range.
