Content	Overview The LB1846M and LB1848M are 2-channel low-voltage, low saturation voltage type bidirectional motor driver ICs that are optimal for use as 2-phase stepping motor drivers in printers, floppy disk drives, and cameras and other portable equipment. The output circuits are of the bipolar type, with pnp transistors in the upper side and npn transistors in the lower side, and they achieve low saturation output and low power characteristics despite being provided in a miniature package. Both of these IC products can directly control a motor from signals from a microcontroller. The LB1846M is optimal for 1-2 phase excitation drive for 2-phase stepping motors using 4-input logic (IN1, IN2, IN3, and IN4) and the LB1848M is optimal for 2-phase excitation drive for 2-phase stepping motors using 3-input logic (ENA, IN1, and IN2). Another point is that these ICs include built-in thermal shutdown circuits so that IC scorching or burning is prevented in advance even if the IC outputs are shorted. Additionally, the MFP-10S miniature package used supports reduced-space mounting. Features •Optimal for 1-2 phase excitation drive for 2-phase stepping motors (LB1846M) •Optimal for 2 phase excitation drive for 2-phase stepping motors (LB1848M) •Low saturation voltage. VO(sat) = 0.55 V typical at IO= 400 mA •Standby current: zero •Thermal shutdown circuit •Miniature package: MFP-10S (6.5 ·5.1 mm2) •Through-current prevention circuit (LB1848M only) •“Soft off” function that reduces power supply line noise when switching from drive to standby modes. (Requires the use of one external capacitor.) (LB1848M only) •No limitations on the magnitude relationship between the power supply voltage (VCC) and the input voltage (VIN) Package Dimensions unit: mm 3086A-MFP10S Monolithic Digital IC Ordering number : ENN5339A 73099TH (OT)/O3096HA (OT) No. 5339-1/8 SANYO Electric Co.,Ltd.
