... TTL/CMOS COMPATIBLE DRIVER HIGH EFFICIENCY CHOPPING MULTIPOWER BCD TECHNOLOGY 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 ...

... OSCILLATOR D2 C2 CIRCUIT DESCRIPTION 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 ...

... 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 ...

... A thermal protection circuit has been included that will disable the device if the junction temperature reach- es 150 °C. When the temperature has fallen to a safe level the device restarts under the control of the input and enable signals. IN1 = H IN2 = H EN1 = H IN1 = X IN2 = X EN1 = L L6204 7/12 ...

... RC filter can be added if necessary. POWER DISSIPATION (each bridge) 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 ...
