Integrator output terminal (speed control terminal).
Varies the switching regulator output votlage.
Integrator input terminal.
Speed discriminator output terminal.
Goes LOW when the specified speed is exceeded.
Suppresses ripples in the motor current during operation of current limiter 2.
Lock detection terminal.
Goes LOW when the motor rotation speed is when the locking range.
FG pulse input (Start/Stop control) terminal.
FG pulse input (4V supply) terminal.
FG amp output termianl.
Crystal oscillator terminal to which a crystal resonator is connected.
5V supply terminal.
Specifications of any and all SANYO products described or contained herein stipulate the performance,
characteristics, and functions of the described products in the independent state, and are not guarantees
of the performance, characteristics, and functions of the described products as mounted in the customer’s
products or equipment. To verify symptoms and states that cannot be evaluated in an independent device,
the customer should always evaluate and test devices mounted in the customer’s products or equipment.
SANYO Electric Co., Ltd. strives to supply high-quality high-reliability products. However, any and all
semiconductor products fail with some probability. It is possible that these probabilistic failures could
