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 modula-
ted 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 complemen-
tary 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, short-
circuit, 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.
