Preliminary specification
5 V spindle & VCM driver combo
TDA5345HT
RECOMMANDED OPERATING CONDITIONS
HANDLING
Inputs and outputs are protected against electrostatic discharge in normal handling. However, to be totally safe, it is
desirable to take normal precautions appropriate to handling MOS devices.
ESD according to MIL STD 883C - method 3015 (HBM 1 500
, 100pF) 3 pulses (+) and 3 pulses (-) on each pin versus
ground - Class 1: 0 to 1 999 V
THERMAL RESISTANCE
This is obtained in a PCB tailored to heat dissipation : pin number 16, 32, 48, 64 have to be connected to a good ground
layer to improve the IC heat dissipation.
