range by the end of the warm-up time that follows reset release, the TMP89FH40 cannot operate properly.
Configuration
Function
The power-on reset circuit generates a reset when the power is turned on. When the supply voltage is lower than
The power-on reset circuit consists of a reference voltage generation circuit and a comparator.
The supply voltage divided by ladder resistor is compared with the voltage generated by the reference voltage
When power supply voltage goes on, if the supply voltage is equal to or lower than the releasing voltage of the
When power supply voltage goes down, if the supply voltage is equal to or lower than the detecting voltage of the
Until the power-on reset signal is generated, a warm-up circuit and a CPU is reset.
When the power-on reset signal is released, the warm-up circuit is activated. The reset of the CPU and peripheral
