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.

Output Shorted to + VS and Overload Detection
An internal circuit detects if the current through the low side transistor is higher than 4 A
typ. In this case all outputs are turned off after 40 µs and the error flag EF is set to
ground.
At a junction temperature higher than 160 °C the thermal shutdown turns off, all four
output stages commonly and the error flag is set without a delay.
Open Load Detection
The output Q1 has a 10 kΩ pull-up resistor and the output Q2 has a 10 kΩ pull-down
resistor. If E1 and E2 are high, all output power stages are turned-OFF. In case of no
load between Q1 and Q2 the output voltage Q1 is VS and Q2 is ground. This state will
be detected by two comparators and an error flag will be set after a delay time of 40 µs.
Changing the inputs resets the error flip flop.
