TB6598FN/FNG

Dual Full-Bridge Driver for Stepping Motors

The TB6598FN/FNG is a 2-phase bipolar stepping motor driver

employing an LDMOS structure with low ON-resistance for

output drive transistors. By applying four input signals (EN1,

EN2, IN1, IN2), it is possible to control the rotation direction

(forward/reverse) of 2-phase/1-2-phase stepper motor.

It is also possible to achieve constant-current drive (PWM

chopper drive).

Features

Weight: 0.07 g (typ.)

Output current: I

≤ 0.8 A (max)

out

Low ON-resistance: 1.5 Ω (upper side + lower side typ. @ V = 5 V)

Constant-current control (PWM chopper drive)

Standby (power-saving) mode

On-chip thermal shutdown circuit (TSD)

Compact package: SSOP-16

TB6598FNG:

TB6598FNG is a Pb-free product.

The following conditions apply to solderability:

*Solderability

1. Use of Sn-37Pb solder bath

*solder bath temperature = 230°C

*dipping time = 5 seconds

*number of times = once

*use of R-type flux

2. Use of Sn-3.0Ag-0.5Cu solder bath

*solder bath temperature=245°C

*dipping time = 5 seconds

*the number of times = once

*use of R-type flux

This product has a MOS structure and is sensitive to electrostatic discharge. When handling the product,

ensure that the environment is protected against electrostatic discharge by using an earth strap, a

conductive mat and an ionizer. Ensure also that the ambient temperature and relative humidity are

maintained at reasonable levels.

Install the product correctly. Otherwise, breakdown, damage and/or degradation in the product or

equipment may result.
