Description
The FAN8100N/FAN8100MTC is a monolithic two channel
dc motor drive IC designed for low voltage operated sys-
tems. It has dual H-bridge drivers, using NPN and vertical-
PNP power transistors with a low saturation voltage. Power
packages with heat sinks endure high continuous output cur-
rent. The high current and low saturation voltage feature
make this device suitable for dc motor applications such as
toy cars. It has also a built-in thermal shutdown protection
circuit with hysteresis.

Application Information
1. Thermal Shutdown (TSD)
Thermal Shutdown Circuit turns OFF all outputs when the junction temperature typically reaches 150
C
. It is intended to pro-
tect the device from failures due to excessive junction temperature.
The Thermal Shutdown has the hysteresis of 40
C
approximately
.
2. Printed Circuit Board (PCB) Layout
If high current flows on the power supply(PVCC) and GND line, it can be misoperated due to the line oscillation.
The following points should be kept in mind regarding as the pattern layout to prevent it.
Making the wiring lines thick and short, especially between power supply (PVCC) and GND.
Putting a passthrough capacitor near the IC
The R
th-ja
of the FAN8100N/MTC can be reduced by soldering the GND pins to a suitable copper area of the printed circuit
board as shown in following figure. It is recommended the copper area is as large as possible.
Example of PCB copper area which is used as heatsink
