EUM6867 General Description
EUM6867 is a pre driver for single coil brushless DC motor, specially designed for 12V power supply application. With an external PWM input signal, EUM6867 can control the speed of DC motor. It is an interface between a HALL IC and a single coil motor. The functions built in EUM6867 include soft start mode, PWM control mode, minimum speed mode, soft-switching time, fan tachometer, lock protection, auto restart, Hall Bias and current limiter.
PWM mode controls the external PMOS-NMOS FET in low noise and low vibration. With soft start function. EUM6867 can drive motor from slow speed to fast speed in a settable time by setting the external capacitor between S-S and 5VREG. Minimum speed mode makes the lowest speed of motor settable. Soft-switching time can cut the ineffective current when phase change is not set. If the motor is stalled by external force or obstacles, overdrive current may incur coil overheat/burning. To prevent this, lock protection circuit can shut down the external power devices for a few seconds after motor lockup. Then auto restart circuit will try to power up these devices. The protection and power up time are settable by an external capacitor. EUM6867 has FG output.
EUP2410 General Description
The EUP2410 is a highly efficient, synchronous, fixed frequency, current-mode step-up converter with output to input disconnect, inrush current limiting and internal soft-start. It includes an error amplifier, ramp generator, comparator, N-Channel switch and P-Channel synchronous rectified switch (which greatly improves efficiency). The output disconnect feature allows the output to be completely isolated from the input in shutdown mode.
The 500KHz switching frequency allows for smaller external components producing a compact solution for a wide range of load currents. The internal compensation and soft-start minimizes the external component count and limits the inrush current during startup. The EUP2410 regulates the output voltage up to 6V and provides up to 600mA from 2.2V input with a 3.3V output.
The EUP2410 is offered in a thin SOT23-5 package.
