description  
HEAT SINK  
The TLS2205 is a combination voice-coil and  
spindle-motor driver with voltage monitor  
integrated circuit. This circuit is designed for  
small-form-factor, high-performance hard disk  
drives. The TLS2205 integrates a three-phase  
brushless dc motor driver with a linear full-bridge  
voice-coil driver. Additional circuitry is added for  
power-up and power-down sequencing of the  
driver amplifiers used for motor speed control. A  
brake function can be invoked on the spindle  
motor after the head is in a safe landing zone.  
External sense resistors are used for precision  
spindle motor and VCM current monitoring.  
Automatic head retract is provided for voltage or  
thermal fault conditions. The TLS2205 operates  
with only 5 V of supply voltage and has a  
sleep-mode option for low-power applications. All
