Notes on items *1 to *3. (1) VDD reset block (*1) * The reset detection function detects the level of VDD5V input to VDD IN. * This reset function operates correctly when the VDD IN voltage is over 0.5 V, but is undefined when VDD IN is under 0.5 V. The reset voltage must never exceed VDD IN. * The allowable range for the threshold voltage has a tolerance of 4.7%. (2) BAT and ACC reset blocks (*2) * These reset detection outputs must operate correctly when the VDD IN voltage is over 2 V. The reset voltages must never exceed VDD IN. * The ACC detection function has no region where detection is unpredictable according to the value of the voltage detected. That is, the low level will be detected correctly when ACC IN is 0 V. * The allowable range for the threshold voltage has a tolerance of 3.2%. (3) Thermal protection and operating temperature (*3) * The values shown are design target values and are not tested.
