Microcontroller support
For easy system integration, the TD340 provides the following functions:
- 5V regulator,
- reset circuit,
- watchdog circuit,
- standby mode,
- temperature indicator.
5V regulator
The TD340 provides a 5V regulated voltage at VOUT pin with a maximum current of 20mA over the whole
Vbatt range (6.5 to 16V). Current can be up to 40 mA with nominal 12V Vbatt.
It is mandatory to connect a 220nF capacitor to the 5V output, even if the 5V output is not used, because
the 5V is internally used by the device. 220nF is the optimized value for the voltage regulator.
Reset circuit
The integrated supervisor circuit resets the micro controller as soon as the voltage of the Micro Controller
decreases below 4.2V, and until the voltage of the micro controller has not passed above 4.3V.
RESET output is active low. It features an open drain with a internal 75k pull up resistor to internal 5V
which allows hardwired OR configuration.
