IXDP631PI IXYS

Inverter Interface and Digital Deadtime Generator for 3-Phase PWM Controls Features Type Package Configuration Temp. Range l 5 V HCMOS logic implementation maintains low power at high speed IXDP630 PI 18-Pin Plastic DIP RC Oscillator -40C to +85C l Schmitt trigger inputs and CMOS IXDP631 PI 18-Pin Plastic DIP Crystal Oscillator -40C to +85C logic levels improve noise immunity l Simultaneously injects equal dead- time in up to three output phases This 5 V HCMOS integrated circuit is In the IXDP630, deadtime programming intended primarily for application in is achieved by an internal RC oscillator. l Replaces 10-12 standard SSI/MSI three-phase, sinusoidally commutated In the IXDP631, programming is logic devices brushless motor, induction motor, AC achieved by use of a crystal oscillator. l Allows a wide range of PWM servomotor or UPS PWM modulator An alternative for both the IXDP630/ modulation strategies control systems. It injects the required 631 is with an external clock signal. l Directly drives high speed deadtime to convert a single phase leg Because of its flexibility, the IXDP630/ optocouplers PWM command into the two separate 631 is easily utilized in a variety of logic signals required to drive the upper brushed DC, trapezoidally commutated Applications and lower semiconductor switches in a brushless DC, hybrid and variable PWM inverter. It also provides facilities reluctance step and other more exotic l 1- and 3- Phase Motion Controls for output disable and fast overcurrent PWM motor drive power and control l 1- and 3- Phase UPS Systems and fault condition shutdown. circuit designs. l General Power Conversion Circuits l Pulse Timing and Waveform Block Diagram IXDP 630/IXDP 631 Generation l General Purpose Delay and Filter l General Purpose Three ChannelOne Sho IXYS reserves the right to change limits, test conditions and dimensions. 1998 IXYS All rights reserved I - 14 OBSOLETEIXDP630 IXDP631 Symbol Definition Maximum Ratings Dimensions in inch (1 = 25.4 mm) min. max. 16-Pin Plastic DIP V Supply Voltage -0.5 7 V CC V DC Input Voltage -0.5 V + 0.5 V IN CC I DC Input Current -1 1 mA IN V DC Output Voltage 0.5 V + 0.5 V 0 CC I DC Output Current -25 25 mA 0 T Storage Temperature -55 150 C stg T Lead Soldering (max. 10 s) 300 C L Recommended Operating Conditions V Supply Voltage 4.5 5.5 V CC T Operating Temperature -40 85 C J l Output Current -8 8 mA 0 f Oscillator Frequency 0.001 16/24 MHz OSC Symbol Definition/Condition Characteristic Values min. typ. max.
