IXDP610 General Description
The IXDP610 Digital Pulse Width Modulator (DPWM) is a programmable CMOS LSI device which accepts digital pulse width data from a microprocessor and generates two complementary, non-overlapping, pulse width modulated signals for direct digital control of switching power bridge. The DPWM is designed to be operated under the direct control of a microprocessor and interfaces easily with most standard microprocessor and microcomputer buses. The IXDP610 is packaged in an 18-Pin slim DP.
The PWM waveform generated by the IXDP610 results from comparing the output of the Pulse Width counter to the number stored in the Pulse Width Latch (see below). A programmable "dead-time" is incorporated into the PWM waveform. The Dead-Time Logic disables both outputs on each transition of the Comparator output for the required dead-time interval.
The output stage provides complementary PWM output signals capable of sinking and sourcing 20 mA at TTL voltage levels. The Output Disable logic can be activated either by software or hardware. This facilitates cycle-by-cycle current-limit, shortcircuit, over-temperature, and desaturation protection schemes.
The IXDP610 is capable of operating at PWM frequencies from zero to 390kHz; the dead-time is programmable from zero to 14 clock cycles (0 to 11 % of the PWM cycle), which allows operation with fast power MOSFETs, IGBTs, and bipolar power transistors. A trade-off between PWM frequency and resolution is provided by selecting the counter resolution to be 7-bit or 8-bit. The 20 mA output drive makes the IXDP610 capable of directly driving opto isolators and Smart Power devices. The fast response to pulse width commands is achieved by
instantaneous change of the outputs to correspond to the new command. This eliminates the one-cycle delay usually associated with other digital PWM implementations.
