Description
TLE 5203 is an integrated power bridge with DMOS output stages for driving DC motors.
This motor bridge is optimized for driving DC motors in reversible operation. The internal
protective circuitry in particular ensures that no crossover currents can occur.
Because the free-wheeling diodes are integrated, the external circuitry that is necessary
is reduced to the capacitors on the supply voltage.
The control inputs have TTL/CMOS-compatible levels.……
