TPS4100A
FOUR CHANNEL BRIDGED OUTPUT POWER STAGE
G E N E R A L D E S C R I P T I O N
The TPS4100A is a 4 channel bridged (16 power transistors) output power stage. The TPS4100A
accepts 5V CMOS logic signals from a Class-T processor, such as TCD6001, to create a high
fidelity 4-channel audio amplifier. The TPS4100A has been designed specifically for automotive
head unit applications operating on a single 10-26V supply.

... Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. See the table below for Operating Conditions. Note 2: Supply voltage is limited in AM Mode due to additional power dissipation of output stage when operating in Class B mode. Please note that the TPS4100A is still fully protected from load dump transients in AM Mode. : The in Note 3 put section pins (pins 1-9, 11,12) should not be connected to voltages over 5 ...

... The TPS4100A is typically configured as a high power, high efficiency, four channel switching amplifier. The TPS4100A also has an additional amplifier mode named “AM Mode.” By pulling the AM pin to a logic high level, the TPS4100A is configured as a Class B amplifier as opposed to the normal, Class-T amplifier ...

... This fault puts the amplifier into mute and resets automatically once the supply voltage is reduced below the hysteresis band. The TPS4100A also has built-in load dump protection. This circuit puts the amplifier into sleep mode if the supply voltage is increased above 30V. The TPS4100A is able to survive power supply spikes to 60V if the duration is less than 50mS. ...

... The SLEEPB (SLEEP) pin is a logic input that when pulled low puts the TPS4100A into a low quiescent current mode. This pin must be pulled external 3. supply to activate (disable sleep mode) the TPS4100A. The sleep pin cannot be pulled up to VPP due to internal circuitry limitations. The amplifier takes approximately 500mS to come out of sleep ...
