Dual Power Supply |
| |
− Positive power: VDD = 4.0V ∼5.5V
− Negative power: VEE = -4.0V ∼-5.5V
|
|
Completed AC Power Control |
| |
− Both phase control and cycle control functions areimplemented in a single IC.
− Power transfer to load is smoothly controlled by externalvolume for whole range of phase angles between
0◦ to 180◦ in phase control mode.
− A control unit can be selected within half period orone period in cycle control mode.
− For given volume level, turn-on cycle period isevenly dispersed for uniformly transfer power to
load in cycle control mode. |
|
Superlative Output Driver |
| |
− Typical triac trigger current is 150mA.
− Quardrant-1 (positive trigger pulse) and quardrant-3 (negative trigger pulse) is used to drive triac.
− Can drive simultaneously more than one triac, iftotal trigger current is not exceed 150mA. |
|
Trigger Pulse Control |
| |
− Trigger pulse width is automatically controlled by
|
|
Automatic Synchronize |
| |
− Reliable recognition of AC zero passage using on chip zero crossing detector
|
|
Wide AC Range
|
| |
− Applicable to any AC voltage or frequency in worldwidecommercial power line.
− Simply adjust external power supply componentsand triac, if AC input voltage is changed.
− Can handle AC input frequency from 30Hz to100Hz |
|
High Performance |
| |
− Maximum off voltage is less than 5V both 100%volume in phase control mode and turn on cycle in
cycle control mode.
− Triac is in completely off state both 0% volume inphase control mode and off cycle in cycle controlmode |
|
Standard Package |
| |
− Provided small standard 16 pin SOP package |
|
Reliable CMOS Technology |
| |
− Operating temperature: -20◦C to +85◦C |
|
Large Application Scope |
