Features

  • The low saturation voltage reduces IC internal heating and allows a high voltage to be applied to the motor. Thus this device can be used even in environments with a high operating ambient temperature. Output saturation voltage: Vsat1 = 0.25V typical (I O = 0.2A) (High side + low side): Vsat2 = 0.55V typical (I O = 0.5A) Operating temperature range: Ta = -30 to +85°C
  • The LB1930M features the wide operating voltage range of 2.2 to 10.8V and the low standby current drain of 0.1μA, and therefore can easily be used in battery operated systems.
  • To minimize through currents, the LB1930M internal logic passes through an internal standby state when switched by the input signals between forward/reverse and brake, or between forward and reverse.
  • There are no constraints on the relationship between the input voltage and the supply voltage. For example, the LB1930M can be used with VCC = 3V, and VIN = 5V.
  • If the IC chip exceeds 180°C due to an output short causing a large current flow, the built-in thermal protection circuit suppresses the drive current to prevent fires or destruction of the IC.
  • MFP-10S miniature package. Also, the LB1930M features the high allowable power dissipation of Pd = 800mW.

Usage Notes Oscillation may occur in the VCC and P-GND lines, since these lines carry a wide range of currents. The following may help if this is a problem. (1) Lower the inductance of the wiring by making lines wider and shorter. (2) Insert capacitors with good frequency characteristics close to the IC. (3) Consider adopting the following methods if the CPU and this IC are mounted on different printed circuit boards that could easily have different ground potentials.

  • Connect S-GND to the CPU ground and connect P-GND to the power system ground.
  • Insert resistors of about 10kΩ in series between the controller outputs and the inputs on this IC. This catalog provides information as of June, 2011. Specifications and information herein are subject to change without notice.
