spindle motor pre-driver combination chip
Product specification
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.

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.
