MB90480/485 Series

(4) Power-on Reset Standards

(VCC

= 2.7 V to 3.6 V, VSS = 0.0 V, TA = −40 °C to +85 °C)

* : Power rise time requires VCC

< 0.2 V.

Notes:

• The above standards are for the application of a power-on reset.

• Within the device, the power-on reset should be applied by switching the power supply off and on again.

Rapid fluctuations in power supply voltage may trigger a power-on reset in some

cases. As shown below, when changing supply voltage during operation, it is rec-

ommended that voltage changes be suppressed and a smooth restart be applied.

The slope of voltage increase

should be kept within 50 mV/ms.
