Application Description
This IC is especially designed to drive inductive loads (relays, electromagnetic valves). Integrated clamp-diodes limit the output voltage when inductive loads are discharged. Four open-drain logic outputs indicate the status of the integrated circuit. The following conditions are monitored and signaled: - Overloading of output (also shorted load to supply) in active mode - Open and shorted load to ground in active and inactive mode - Overtemperature
Circuit Description
Input Circuits The control and enable inputs, both active high, consist of schmitt triggers with hysteresis. All inputs are connected with pull-down current sources. Not connected inputs are interpreted as LOW. In standby mode (STBY = LOW) the current consumption is greatly reduced. The circuit is active when STBY = HIGH. If the standby function is not used, it is allowed to connect the standby pin directly to VS. Switching Stages The four power outputs consist of DMOS-power transistors with open drains. The output stages are shorted loads protected throughout the operating range. Integrated clamp-diodes limit voltage overshoots produced when inductive loads are demagnetized. Parallel to the DMOS transistors there are internal pull down resistors. They are provided to detect an open load condition in the off state. They will be disconnected in the standby mode. Protective Circuits The outputs are protected against current overload and overtemperature. There is no protection against reverse polarity of the supply voltage. Error Detection The status outputs indicate the switching state under normal conditions (LOW = off; HIGH = on). If an error occurs, the logic level of the status output is inverted, as listed in the diagnostic table below. The state of the error detection circuits is directly dependent on the input status. If current overload or overtemperature occurs, the error condition is stored into an internal register and the output is shutdown. The reset is done by switching off the corresponding control input. Open load is detected for all four channels in on and off mode. In the on mode the load current is monitored. If it drops below the specified threshold value, then an open load condition is detected.

Datasheet TLE 6216
In the off mode, the output voltage is monitored. An open load condition is detected when the output voltage of a given channel is below 55 % of the supply voltage VS. Also the output voltages of two outputs are compared against each other in off condition with a fixed offset of typ. 1.25 V to recognize GND bypasses. To suppress fault diagnosis during the flyback phase of the compared output, the diagnostic circuit includes a latch function. Reset of this latch is done at end of the flyback phase, additionally it can be reset by a low signal on the enable input or a high signal of the input line. See block diagram of open load detection on page 4.
Diagnostic Table
In general the status follows the input signal in normal operating conditions. If any error is detected the status is inverted.
