DC-Motor Controller
2. Electrical Characteristics
2.1 Operating Conditions
Following characteristic is valid over the temperature -40deg C<TA<125deg C and supply voltage range of
7.3<VS<18V, unless otherwise noted. With VS ≤ VSmin but above reset state or inside a temperature range
125deg C<TA<150grdC the controller works correctly, analogue parameters can not be fully guaranteed. If
several pins are charged with transients above VS and below VSS, the summary of all substrate currents of
the influenced pins must not exceed 10mA for correct operation of the device. All voltages refer to ground of
IC, which is built by short of all existing ground pins, which were split to meet EMC performance and lowest
possible noise influence.

Table 1 - Operating Conditions
(*) Target temperature after qualification: With temperature applications at TA>125deg C a reduction of chip
internal power dissipation with external supply transistor is obligatory. The extended temperature range is
only allowed for a limited periods of time, customers mission profile has to be agreed by Melexis as an
obligatory part of the Part Submission Warrant (PSW). Some analogue parameter will drift out of limits, but
chip function can be guaranteed.
