U6803B Triple-Driver with Thermal Monitoring Description The triple-driver IC includes three non inverted and current limited output stages with an open collector. Common thermal shutdown protects outputs against critical junction temperature. Each output can sink 20 mA, parallel output operation is possible. The digital inputs have Schmitt-trigger function with pull-up current sources to 5 V. Features D Three input comparators with Schmitt-trigger characteristic D ESD protection to human body model: D Output stages: D Input clamping current capability to 10 mA D Integrated protection cells (EMC, ESD, RF) dedicated to all input stages " "2000 V (C = 100 pF, R = 1.5 kW) – Short circuit protected with diode – Load-dump protected @ 1 kW – Clamping current @ –2 mA – Jump start possible D Common shutdown by junction temperature monitor D Low voltage reset with hysteresis – No crosstalk on adjacent channels Ordering Information Extended Type Number U6803B–FP Package SO8 Remarks Block Diagram / Applications VO1 1 VO2 3 VO3 4 VS 7 Thermal shutdown 2 GND Under voltage detection VS=5 V 8 VI1 6 VI2 Figure 1. 5 VI3 13332 VS TELEFUNKEN Semiconductors Rev.
