Hookup Examples
Warning: As activating both sides of an H-Bridge circuit may cause short-circuit current flow, it is
imperative that the two EDE1204 pins labeled 'Coil A' be connected as inputs to one H-Bridge,
and the two EDE1204 pins labeled 'Coil B' be connected as inputs to the other H-Bridge.
Connection via L293 H-Bridge IC (full EDE1204 schematic not shown)
In this first example, The EDE1204 is paired with a L293 Dual H-Bridge IC. The L293 can supply
up to 1A per coil. A variant of the L293, the L293D, includes the output clamping diodes within
the IC. This arrangement is ideal for many applications as it provides a two IC drive circuit.
Pinout for the L293 IC is as follows:
Pin 1: Chip Inhibit
Pin 2: Input 1
Pin 3: Output 1
Pin 4: GND
Pin 5: GND
Pin 6: Output 2
Pin 7: Input 2
Pin 8: Vc (Collector Supply Voltage)
Pin 9: Chip Inhibit 2
Pin 10: Input 3
Pin 11: Output 3
Pin 12: GND
Pin 13: GND
Pin 14: Output 4
Pin 15: Input 4
Pin 16: Vss (Logic Supply Voltage, +5V)
