Functional Descriptions
System Standby built-in regulator turned under control high/low state STBYB pin. When STBYB low, regulator will turned off, when that high, regulator will turned Also, signal initializes internal logic When STBYB low, internal logic initialized, when STBYB high, into normal operation. Mute Function mute function provided mainly mute output that impulse noise will appear output when power supply being turned Output muting output signal turned setting MUTEB high low. When MUTEB low, output stopped (all output signals high-impedance state) when MUTEB high, placed normal operation mode. Also NOD_OUTSHDNB (Nch open drain) signal output external monitor pin. Power-on sequence power-on sequence must controlled timing shown below (PWM=BD mode) minimize impulse noise. Note that when MUTE released, input signals must held low.
NOD_OUTSHDNB (Nch open drain) output signal generated (Nch open drain output turned when output shut down (except when overcurrent protection circuit activated). This operating condition established when either following conditions occurs: Thermal shutdown circuit activated. power voltage protection circuit activated. MUTEB (all outputs muted)

Power Down Sequence power shut-down sequence must controlled timing shown below (PWM=BD mode) minimize impulse noise.
Protection Circuits LV4920H full complement built-in protection circuits: overcurrent protection, thermal protection, power supply voltage protection circuits. Overcurrent protection circuit overcurrent protection circuit protects output transistors detecting current that exceeds predetermined value load shorting, shorting power, shorting ground, etc. When protection circuit activated, both high- low-side output transistors turned output placed high-impedance state. figure below shows waveform current that flows when load shorting occurs.

LV4920H
Thermal protection circuit thermal protection circuit detects temperature (150°C higher) inside protects from thermal damage. When protection circuit activated, both high- low-side output transistors turned off, placing output into high-impedance state. This protective operation given hysteresis. Also, NOD_OUTSHDNB (Nch open drain) signal output external monitor pin. power supply voltage protection circuit power supply voltage protection circuit turns both high- low-side output transistors place output into high-impedance state when power supply voltage (PVD) falls below predetermined value (6.7V lower). This operation (activating protective circuit when rises beyond 7.5V) given hysteresis (0.8V greater). Also, NOD_OUTSHDNB (Nch open drain) signal output external monitor pin.
