5.4 Undervoltage Lockout (UVLO) Circuit
This function is to forcibly stop the operation of the IC to prevent malfunctioning if V
DD
drops.
If V
DD
drops abruptly in the order of several
μ
s, this function may not operate.
5.5 Overheat Protection (TSD) Circuit
This function is to forcibly stop the operation of the IC to protect it from destruction due to overheating if the chip
temperature of the IC rises.
The overheat protection circuit operates when the chip temperature rises to 150
°
C or more. When overheat is
detected, all the circuits are stopped. When reset is performed or when UVLO is detected, the overheat protection
circuit does not operate.
5.6 Power Up Sequence
This IC has a circuit that prevents current from flowing into the V
M
pin when V
DD
= 0 V. Therefore, the current that
flows into the V
M
pin is cut off when V
DD
= 0 V.
Because the V
DD
pin voltage and V
M
pin voltage are monitored, a current of 3
μ
A MAX. flows into the V
M
pin when
V
DD
is applied.
