Fairchild Semiconductor International (San Jose, CA) introduced the FAN8200, a two-channel drive IC suitable for two-phase stepping motor drive system applications, including PC and digital cameras, disk drives, thermal printers, and motion controllers.
The FAN8200 features integrated dual H-bridge drivers with vertical PNP power transistors resulting in low saturation voltage (0.4V at 0.4A) and optimum thermal characteristics for high-efficiency operation over a wide supply-voltage range. In addition, the device features built-in, shoot-through current protection to minimize spikes on the power supply and a thermal shutdown function. The FAN8200 accommodates either a 3.3V or 5V MPU control input and provides an independent chip-enable input for each bridge, allowing the device to also be applied as a low-voltage, general-purpose power driver.
The FAN8200, with a maximum rating of 1W, is offered in a through-hole, 14-pin, DIP-300 package. The surface-mount version of the device, the FAN8200D, is rated at 600mW and is offered in a 14-pin, SOP-225 package. Both versions are rated for operation over -20 to +75 degrees C.
Available now, the FAN8200 is $0.80 in the DIP-14, and $0.78 in the SOP-14, for 1,000-piece units. Delivery is 8 to 10 weeks ARO.
