driver current 1 A Integrated free-wheeling diodes Short-circuit proof to ground Inhibit ESD protected inputs Temperature range – 40 °C ≤ Tj ≤ 150 °C P-DIP-18-3 P-DSO-20-6 Type TLE 4205 TLE 4205 G Description TLE 4205 is an integrated power full-bridge DC-motor driver for a wide temperature range, as required in automotive applications for example.
The circuit contains two power comparators that can be combined to a full-bridge circuit.
For inductive loads there are integrated free-wheeling diodes to + VS and ground.
The outputs are shortcircuit proof up to 18 V supply voltage to ground and turn off when overtemperature occurs.
This IC is especially suitable for headlight-beam adjustment in automobiles.
