STA533WF 18-volt, 3-amp, quad power half-bridge Features Multipower BCD technology Low input/output pulse width distortion 200-m R complementary DMOS output dsON stage CMOS-compatible logic inputs Thermal protection Thermal warning output PowerSSO36 package with exposed pad down Undervoltage protection Short-circuit protection loads with 10% THD at V =18V in CC single-ended configuration. Description It can also deliver 20 W + 20 W into 8- loads The STA533WF is a monolithic quad half-bridge with 10% THD at V = 18 V in BTL configuration CC stage in multipower BCD technology. The device or, in single parallel BTL configuration, 40 W into can be used as a dual bridge or reconfigured, by a 4- load with 10% THD at V = 18 V. CC connecting pin CONFIG to pins VDD, as a single The input pins have a threshold proportional to bridge with double-current capability. the voltage on pin VL. The device is designed for the output stage of a The STA533WF comes in a 36-pin PowerSSO stereo Full Flexible Amplifier (FFX). It is package with exposed pad down (EPD). capable of delivering 10 W x 4 channels into 4- Table 1.
