1. To properly reset the device, VPS_Main must be tied to 0V before executing the start-up sequence.
2. Compliant with JEDEC standard J-STD-020D (for small-body, Sn-Pb or Pb assembly), the ST ECOPACK®
7191395 specification, and the European directive on Restrictions on Hazardous Substances (RoHS
directive 2011/65/EU of July 2011).
3. Depending on the thermal resistance of package.
Note:
Stresses listed above may cause permanent damage to the device. This is a stress rating only and functional
operation of the device at these or any other conditions above those indicated in the operational sections of the
specification is not implied.
Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
