STA508 is a monolithic quad half bridge stage in Multi-power BCD Technology. It has the features of minimum input output pulse width distortion, 200mΩ RdsON complementary DMOS output stage, CMOS compatible logic inputs, thermal protection, thermal warning output and under voltage protection.
The STA508 is a monolithic quad half bridge stage designed using Multipower BCD technology. It is particularly suited for the output stage of stereo All-Digital High Efficiency (DDX) amplifiers, capable of delivering 80 + 80W at THD = 10% on an 8Ω load with a Vee of 35V.
| Supply Voltage (Vcc) | 10 to 36 V |
|---|---|
| Short Circuit Current Limit | 4.5 A (Typ.) |
| Undervoltage Protection Threshold | 7 V |
| Operating Temperature Range | -40 to 90 °C |
| Thermal Resistance Junction-Case | 1.5 °C/W |
Connecting the CONFIG pin to Vdd reconfigures the device as a single bridge with double current capability.
A logical value of 0 on the FAULT pin indicates that a fault has been detected, such as a short circuit or thermal issue.
The output minimum pulse width at no load is between 70 ns and 150 ns.
