Motor Relay Driver
The motor relay driver MR is controlled by the MRA input signal and the internal control
logic. A logic High at the MRA input switches the MR low side switch on, a logic Low
signal switches it off. However the supervision logic overrules the MRA input condition.
Please see also Table 1 on Page 19 and Table 2 on Page 28.
The output is an open collector output and can sink up to 500 mA. It is protected against
overtemperature and overcurrent and short circuit prove to U_Z. Even the output is
switched off by the supervision logic at U_ZP overvoltage externally a free wheeling diode
is required to protect the output against switching off inductive loads.
