TLE4205

1-A DC Motor Driver Overview Features ● Max. driver current 1 A ● Integrated free-wheeling diodes ● Short-circuit proof to ground ● Inhibit ● ESD protected inputs ● Temperature range – 40 °C ≤ Tj ≤ 150 °C TLE 4205 Bipolar IC P-DIP-18-3 Type TLE 4205 TLE 4205 G Ordering Code Q67000-A9025 Q67006-A9114 Package P-DIP-18-3 P-DSO-20-17 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 short- circuit 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.
