STA505 40V 3.5A QUAD POWER HALF BRIDGE s MINIMUM INPUT OUTPUT PULSE WIDTH DISTORTION 200mΩ RdsON COMPLEMENTARY DMOS OUTPUT STAGE CMOS COMPATIBLE LOGIC INPUTS THERMAL PROTECTION THERMAL WARNING OUTPUT UNDER VOLTAGE PROTECTION MULTIPOWER BCD TECHNOLOGY s s s s s PowerSO36 ORDERING NUMBER: STA505 DESCRIPTION STA505 is a monolithic quad half bridge stage in Multipower BCD Technology. The device can be used as dual bridge or reconfigured, by connecting CONFIG pin to Vdd pin, as single bridge with double current capability, and as half bridge (Binary mode) with half current capability. The device is particularly designed to make the outAUDIO APPLICATION CIRCUIT (Dual BTL) IN1A IN1A +3.3V IBIAS CONFIG PWRDN R57 10K R59 10K C58 100nF TH_WAR PWRDN FAULT 29 23 24 TRI-STATE w C58 100nF w IN1B C53 100nF C60 100nF IN2A IN2B w TH_WAR IN1B VDD VDD VSS VSS VCCSIGN VCCSIGN IN2A GND-Reg IN2B GNDSUB .D 25 27 26 28 30 21 22 33 34 35 36 31 20 19 PROTECTIONS & LOGIC t a M3 S a 15 17 16 14 12 11 10 13 7 e h VCC1A C30 1µF OUT1A OUT1A GND1A VCC1B C31 1µF OUT1B OUT1B put stage of a stereo All-Digital High Efficiency (DDX™) amplifier capable to deliver 50 + 50W @ THD = 10% at Vcc 30V output power on 8Ω load and 80W @ THD = 10% at Vcc 36V on 8Ω load in single BTL configuration.
