15 / 28 page 1996 May 06 15 Philips Semiconductors Product specification 12 V Voice Coil Motor (VCM) driver and spindle motor pre-driver combination chip TDA5149G 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 1500 Ω, 100 pF) 3 pulses positive and 3 pulses negative on each pin versus ground - Class 1: 0 to 1999 V. THERMAL CHARACTERISTICS Note 1. This is obtained in a standard PCB: standard PCB size: 100 mm × 75 mm × 1.6 mm; material = glass epoxy FR4, single copper layer. With dedicated PCB tailored to heat dissipation, the thermal resistance could be as low as 40 K/W.
