FAN8100N/FAN8100MTC
Low Voltage/Low Saturation 2-CH DC Motor Driver
Features
• Two channel H-bridge drivers with built-in NPN and
vertical-PNP power transistors
• Four functions for each channel - Forward/Reserve/Stop/
Brake functions
• Special output pin for an RC car application - for a Turbo
function for Ch.A (five-function RF receiver chip RX-2
interface)
• Low stand-by current (typ. 0.1uA)
• Wide supply voltage range (PVCC=1.8V ~ 9.0V) suitable
for battery operated applications
• 3.3V and 5V micro-controller interface
• Low output saturation voltage (upper and lower total : typ.
0.15V@ 0.2A)
• High current outputs (max. 1.5A/Ch.)
• Parallel connection (Max Current : 3A)
• High thermal capability for high continuous output
currents
• Built-in spark killing diodes
• Built-in a thermal shutdown(TSD) function with
hysteresis
• Short circuit protected
• Temperature independent internal voltage reference
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.
