The TH3122 consists a low drop voltage regulator 5V/100mA and a K-Bus transceiver. The transceiver is suitable for K-Bus systems conform to ISO 9141.
The combination of voltage regulator and bus transceiver in combination with the monitoring functions make it possible to develop simple, but powerful and cheap nodes in K-Bus systems.
The wide output current area and the configurable reset time and reset voltage works together with many different microcontrollers. |
