Sanyo LB8620M Specifications

Ordering number:EN3986

Monolithic Digital IC

LB8620M

Low-voltage/Low-saturation Bidirectional

Motor Driver

Overview

The LB8620M is a low-voltage, low-saturation, two
motor driver with a bidirectional braking function that
provides constant-voltage regulated output for bidirec­tional operation.
The design of the LB8620M is ideal for video equipment,

cameras, and other portable equipment.

Features

• Wide operating voltage range : 4.5V to 7V.
: 3.0V to 7V (unregulated).

• Low saturation voltage.
V

=1V at IO=1A (typ).

sat

• Consumes almost no current in standby mode.
(0.1µA or less).

• Brake function built in.

• Permits setting of bidirectional constant-voltage
regulated value. Four independently ajustable.

• Spark killer diodes built in.

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
give rise to accidents or events that could endanger human lives, that could give rise to smoke or fire,
or that could cause damage to other property. When designing equipment, adopt safety measures so
that these kinds of accidents or events cannot occur. Such measures include but are not limited to protective
circuits and error prevention circuits for safe design, redundant design, and structural design.
