Features
Dual power supply voltage design (5/12V) and wide voltage
handling range
Built-in Hall amplifier with hysteresis (supports core
without auxiliary electrode)
Built-in lockup protection and automatic recovery circuits
(External capacitor for rotation detection need only be 0.1
F, allowing compact, cost-saving design)
Built-in FG output (Vosat = 0.2Vtyp at I
O
= 5 mA)
Built-in output transistor with output withstand voltage
24Vmin/output current 500 mA (average), 1.2A (peak)
Built-in thermal protection circuit
Compact, high-temperature resistant MFP-10 package
reduces external parts count and mounting space, therefore
making this IC support the motors with a wide range of
sizes and speeds.
Ordering number : ENN6115
Overview
The LB1967M is a brushless motor driver IC for 2-phase half-
wave drive well suited for compact fan motor for communica-
tion and office equipment, etc.

Sample Application Circuit
5/12V power supply (3.8 to 17V)
Precautions
Wiring layout for IN
and OUT1 must be designed to prevent interference.
If the wiring between the Hall element and the IC input is long, noise interference may lead to chattering in the FG
output waveform. In this case, insert a capacitor with 0.01 to 0.001
F between IN
+
and IN
.
If CT pin is connected to GND, the lockup protection and restart functions are disabled.
In a circuit configuration as shown above, a current-GND reverse connection will cause a current to flow as follows:
GND -> OUT -> coil -> power supply. The magnitude of this current is limited by the coil resistance. If it is less
than 500 mA, the IC will not be destroyed. If required, insert a diode between V
CC
and the coil.
