DESCRIPTION
The L6204 is a dual full bridge driver for motor
control applications realized in BCD technology
which combines isolated DMOS power transistors
with CMOS and Bipolar circuits on the same chip.
By using mixed technology it has been possible to
optimize the logic circuitry and the power stage to
achieve the best possible performance.
The logic inputs are TTL/CMOS compatible. Both
channels are controlled by a separate Enable.

The L6204 is mounted in an 20-lead Powerdip and
SO 24+2+2 packages and the four center pins are
used to conduct heat to the PCB. At normal oper-
ating temperatures no external heatsink is re-
quired.

... L6204 is a dual full bridge IC designed to drive DC motors, stepper motors and other inductive loads. Each bridge has 4 power DMOS transistor with R (see fig. 3) The 4 half bridges can be controlled independently by means of the 4 inputs IN!, IN2, IN3, IN4 and 2 en- able inputs ENABLE1 and ENABLE2. External connections are provided so that sensing resistors can be added for constant current chopper applications ...

... When the output switches from high to low, a current spike is generated associated with the capacitor C1. On the low-to-high transition a spike of the same polarity is generated by C2, preceded by a spike of the opposite polarity due to the charging of the input capacity of the lower POWER DMOS transistor (see fig. 2). ...

... It is also possible to operate two or more L6204s using only 2 diodes and 2 capacitance for all the ICs; all the Vboot pins are connected to the Cs- tore capacitance while the pin 11 (VCP) of just one L6204 is connect to C have to be connected to the same V Figure 3 ...

... In order to achieve the high performance provided by the L6204 some attention must be paid to ensure that it has an adequate PCB area to dissipate the heat. The first stage of any thermal design is to calculate the dissipated power in the appl ication, for this example the half step operation shown in figure 7 is con- sidered ...
