Monolithic Digital IC
Stepping Motor Driver IC
Overview
The LB1801CL is a 2-channel low-saturation drive low-voltage operation forward/reverse motor driver IC.
Its ultraminiature package makes it optimal for 2-phase excitation drive of 2-phase bipolar stepping motors which are
commonly used in various portable devices such as digital still cameras.
Features
• Low saturation voltage, VO (sat) = 0.3V typ. at IO of 150mA
• Built-in through current prevention circuit
• Zero current drawn in standby mode
• On-chip index comparator (open collector output)
• On-chip ENA interlocked power supply
• Built-in thermal shutdown circuit
• ECSP2828-12 ultraminiature leadless package (2.8mm×2.8mm×0.8mm typ)
Absolute Maximum Ratings at Ta = 25°C
