Block Description and Electrical Characteristics
Power Driver
The TLE 6210/TLE 6211 includes 3 open drain outputs for loads up to 0.5 A: The two
drivers VR and MR are intended for (valve and motor) relays, while the SILA/NSILA
output is designed for a lamp.
In the TLE 6210 GW the SILA output is available. The output goes low if the supply
voltage U_ZP is no longer available – the DMOS is switched on automatically. In the
TLE 6211 GW the NSILA has the inverted polarity related to SILA. In bare dice both
outputs SILA and NSILA can be used.

Valve Relay Output VR
The valve relay output VR is switched On after the power up reset and valid watchdog
signals. The driver has an open drain configuration and can supply up to 500 mA. The
output is protected against overtemperature and overcurrent. The output is short circuit
protected to U_Z. The output stage is equipped with its own overtemperature protection.
In case of overvoltage at the supply U_ZP the output is switched off. However the output
is not protected against overvoltages caused by switching inductive loads. Therefore
externally a free wheeling diode is required as shown in the application diagram.
The valve relay output VR is controlled by the internal supervision logic. If any watchdog
errors or supply over-voltage is detected or the 5 V regulator is out of range, the VR is
switched off (please see also Table 1 on Page 19 and Table 2 on Page 28).
