The ROHM Semiconductor BA5947FM-E2 is a silicon monolithic integrated circuit designed as a power driver for compact disc players. This 4-channel BTL driver utilizes an HSOP-M28 power package, enabling set downsizing.
Key features include three channels directly connected to PWM input with a built-in primary filter, and a fourth channel (CH4) with input switching capability via the SW terminal. It offers a wide dynamic range, a built-in thermal shutdown circuit, and independent power supplies for different channel pairs (PreVcc, PowVcc for CH1/CH2, and PowVcc for CH3/CH4) for efficient power supply voltage design. An external mute terminal allows for output current muting, and a general operational amplifier is integrated within the device.
The device operates within a temperature range of -35°C to 85°C and is available in a 28-SOP package with heat tabs. It is suitable for applications involving DC motors and general-purpose use, with a load type specified as inductive.
