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.
