Description

STA516B is a monolithic quad half-bridge stage in

multipower BCD technology. The device can be

used as dual bridge or reconfigured, by

connecting pin CONFIG to pins VDD, as a single

bridge with double-current capability or as a half

bridge (binary mode) with half current capability.

The device is designed, particularly, to be the

output stage of a stereo all digital high efficiency

amplifier. It is capable of delivering 200 W +

200 W into 6  loads with THD = 10% at

= 51 V or, in single BTL configuration, 400 W

into a 3 load with THD = 10% at V

= 52 V.

The input pins have a threshold proportional to

the voltage on pin VL.

The STA516B is aimed at audio amplifiers in hi-fi

applications, such as home theatre systems,

active speakers and docking stations.

It comes in a 36 pin PowerSO package with

exposed pad up (EPU).

STA516B 4 Power supply and control sequencing Power supply and control sequencing To guarantee correct operation and reliability, the recommended power-on sequence as given below should be followed:  Apply VCC and VL, in any order, keeping PWRDN low in this phase  Release PWRDN from low to high, keeping TRISTATE low (until VDD and VSS are stable)  Release TRISTATE from low to high Always maintain PWM inputs INxy < VL.

STA516B 5 Technical information Technical information The STA516B is a dual channel H-bridge that is able to deliver 200 W per channel (into RL = 6  with THD = 10% and VCC = 51 V) of audio output power very efficiently. It operates in conjunction with a pulse-width modulator driver such as the STA321 or STA309A. The STA516B converts ternary, phase-shift or binary-controlled PWM signals into audio power at the load.
PAGE 12
Technical information 5.2 STA516B Protection circuitry The STA516B includes protection circuitry for overcurrent and thermal overload conditions. A thermal warning pin (THWARN, pin 28, open drain MOSFET) is activated low when the IC temperature exceeds 130 °C, just in advance of thermal shutdown. When a fault condition is detected an internal fault signal immediately disables the output power MOSFETs, placing both H-bridges in a high-impedance state.

STA516B 6 Applications Applications Figure 9 below shows a single-BLT configuration capable of giving 400 W into a 3  load at 10% THD with VCC = 52 V. This result was obtained using the STA30X+STA50X demo board. Note that a PWM modulator as driver is required. Figure 9.
