C1237HA – Speaker Protection IC for Stereo Power AMP

C1237HA – Speaker Protection IC for Stereo Power AMPOverview:C1237HA is a monolithic integrated circuit designed for protecting stereo power amplifier and loudspeaker. Package/Case 8 Pin Plastic Slim SIP.Features:Work stably within a wide power supply voltage range. (VCC = 25 to 60V)Contain a relay driver. (Max. I6 = 80mA)Work as either latching function or automatic resetting function by using pin3. (In both overload detection and output offset detection, either function can be selected.)Need only single power supply.Both positive and negative output offset can be detected through the same pin. (Output offset detection through pin 2)AC voltage can be detected. (For AC-Power-OFF mute through pin 4)The time delay from amplifier power ON to relay ON can be freely set by selecting external components. (For AC-Power-ON mute through pin 7)The moment that amplifier-power is turned off, it can make relay broke OFF and then loudspeaker disconnected from amplifier to prevent a shock off noise.Applications:Speaker ProtectionPower AmplifierDatasheet:To download datasheet, Please click Here
