2 GENERAL DESCRIPTION

The OM5428 is a bipolar integrated circuit delivering negative pulses for triggering a triac. The flexibility of the circuit makes it suitable for a variety of applications, such as:

• Synchronous on/off switching

• Phase control

• Time-proportional control

• Temperature control

• Motor speed control

FEATURES

• Adjustable proportional range

• Adjustable hysteresis

• Adjustable firing burst repetition time

• Adjustable pulse width

• Supplied from the mains

• Provides supply for external temperature bridge

• Low supply current, low dissipation
