All rights reserved. www.rohm.com TSZ22111・15・001 16.Dec.2015 Rev.001 Absolute Maximum Ratings (Ta=25°C) Parameter Symbol Rating Unit Power Supply Voltage VCC 10.0 V Input Voltage VIN VCC+0.3 to GND-0.3 V Power Dissipation Pd 0.94 (Note) W Storage Temperature Tstg -55 to +150 °C (Note) This value derates by 7.5mW/°C for Ta=25°C or more when ROHM standard board is used. Thermal resistance θja = 133.3(°C/W) ROHM Standard board Size :70 x 70 x 1.6(mm3) Material : A FR4 grass epoxy board(3% or less of copper foil area) Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over the absolute maximum ratings.
