LB1935CL
Monolithic Digital IC
Stepping Motor Driver IC
Overview
LB1935T/LB1935CL is IC with forward/reverse motor drive 2-channel in which low saturation voltage and low voltage
operation possible. Its small sized package is optimal for 2 phase excitation drive of 2 phase bipolar stepping motors for
various portable devices such as digital still cameras.
Features
• Low saturation voltage, VO(sat) = 0.3V typ at IO = 150mA
• Built-in shoot-through current protection circuit
• No standby current consumption (or zero)
• Built-in thermal shutdown circuit
• MSOP10 small-sized package (3.0mm×4.9mm×1.1mm typ) [LB1935T]
• ECSP2828-10 ultraminiature leadless package (2.8mm×2.8mm×0.8mm typ) [LB1935CL]
