TB6557FLG

TOSHIBA BiCD Integrated Circuit Silicon Monolithic

TB6557FLG

DC Motor Driver

The TB6557FLG is a driver IC for driving DC motors. Its

employs LDMOS devices with low ON resistance for output drive

transistors. The TB6557FLG incorporates two constant

current-controlled H-bridge drivers and four voltage-controlled

H-bridge drivers, making it ideal for controlling Zoom/AF/IRIS

lens motors in digital still cameras and camcorders. It supports

three-wire serial data to control motors, thus reducing the

number of lines for interfacing the control IC.

Features

•

Motor power supply voltage: V ≤ 15 V (max)

Weight: 0.08 g (typ.)

Control power supply voltage: V

= 2.7 to 6 V

Output current: I

≤ 0.8 A (max)

out

P-/N-ch LDMOS complementary output transistors

Output ON resistance: Ron (upper + lower) = 1.5 Ω (typ.)

High-speed PWM chopping control at 100 kHz or higher (constant-current H-SW)

Independent standby (Power save) feature

Two 6-bit DACs for setting current value for constant-current H-SW

Thermal shutdown (TSD) protective circuit

Circuit for preventing malfunction at low voltage (shuts down internal circuits at UVLO: V

Small QON-36 package (0.5-mm lead pitch)

≤ 2.2 V (typ.)).

Supports Pb-free reflow mounting

The TB6557FLG is a Pb-free product.

The following conditions apply to solderability:

*Solderability

1. Use of Sn-63Pb solder bath

*solder bath temperature = 230ºC

*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 = 245ºC

*dipping time = 5 seconds

*number of times = once

*use of R-type flux

Note: This product has a MOS structure and is sensitive to electrostatic discharge. When handling this 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.
