| Content | TB6557FLG 2006-6-26 1 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: VM ≤ 15 V (max) • Control power supply voltage: VCC = 2.7 to 6 V • Output current: Iout ≤ 0.8 A (max) • 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: VCC ≤ 2.2 V (typ.)). • Small QON-36 package (0.5-mm lead pitch) • Supports Pb-free reflow mounting 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. Weight: 0.08 g (typ.) The TB6557FLG is a Pb-free product. The following conditions apply to solderability: *Solderability 1. Use of Sn-37Pb 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 |
