Note:
Please be careful about the thermal conditions during use, like operating current, PCB conditions, ambient temperature,
etc.
This IC may be broken if it is soldered at wrongly rotated position because high voltage is applied to low voltage part.
Please be sure that 1PIN position and PCB pattern is correct before soldering process.

Protection Function
(1)
Thermal shutdown circuit
While Tj
=
150°C, all outputs are OFF. To turn-on, change the state of the
STANDBY
pin in the
order of H, L, H.
It has temperature hysteresis to prevent the output from oscillating. (∆T
=
35°C)
POR (Power-On Reset Circuit: V
M
and V
DD
power supply monitor circuit)
Output is forcibly turned off until V
M
and V
DD
reach their specified levels.
ISD
Output is forcibly turned off when current higher than the specified level flows in the output block.
To turn-on, change the state of the
STANDBY
pin in the order of H, L, H.
