STA516B is a 65-volt, 7.5-amp, quad power half bridge with features such as low input/output pulse-width distortion, 200 mΩ RdsON complementary DMOS output stage, CMOS-compatible logic inputs, thermal protection, thermal warning output, and undervoltage protection. It is intended for the output stage of a stereo all-digital high-efficiency amplifier and can deliver 200 W + 200 W into 6-Ω loads with THD = 10% at VCC = 51 V or 400 W into a 3-Ω load with THD = 10% at VCC = 52 V.
The STA516B is a 65-volt, 7.5-amp quad power half bridge device manufactured by STMicroelectronics using Multipower BCD Technology. It features low input/output pulse-width distortion and includes built-in protection mechanisms such as thermal shutdown, undervoltage protection, and overcurrent limiting.
The device is intended for the output stage of stereo all-digital high-efficiency amplifiers in Hi-Fi applications like home theatre systems and active speakers. It can be configured as a dual bridge or reconfigured to operate as a single bridge with double-current capability or as a half bridge.
| Supply voltage (Vcc) | 10 to 58 V |
|---|---|
| Output current limit (Isc) | 7.5 A |
| Undervoltage protection threshold | 7 V |
| Overvoltage protection threshold | 61 to 62.5 V |
The maximum DC supply voltage for pins 4, 7, 12, and 15 is 65 V.
The thermal warning output activates to indicate that the IC temperature is above 130 °C.
Yes, by connecting pin CONFIG to pins VDD, it can operate as a single bridge with double-current capability.
