SI9961ACY Product Details

DESCRIPTION 

The Si9961A is a linear actuator (voice coil motor) driver suitable for use in disk drive head positioning systems. The Si9961A contains all of the power and control circuitry necessary to drive the VCM that is typically found in 31/2 inch hard disk drives and optical disk drives. The driver is capable of delivering 1.8 A at a nominal supply of 12 V. 

The Si9961A provides all necessary functions including a motor current sense amplifier, a loop compensation amplifier and a power amplifier featuring four complementary MOSFETs in a H-bridge configuration. The output crossover protection ensures no cross-conducting current and true Class B operation during linear tracking. Externally programmable gain switch at the input summing junction increases the resolution and dynamic range for a given DAC. The head retract circuitry can be activated by either an undervoltage condition or an external command. An external resistor is required to set the VCM current during retract. 

The Si9961A is constructed on a self-isolated BiC/DMOS power IC process. The IC is available in both standard and lead (Pb)-free, 24-pin SO packages for operation over the commercial, C suffix (0 to 70 °C) temperature range.
