PBL3771N datasheet

 

Description

The PBL3771, PBL3771N is a switch-mode, constant-current driver IC (chopper) with two channels, one for each winding of a two-phase stepper motor. The circuit is especially developed for use in microstepping applications in conjunction with the matching dual DAC (Digital-to-Analog Converter) PBM 3960. A complete driver system consists of these two ICs, a few passive components and a microprocessor for generation of the proper control and data codes required for microstepping.

The PBL3771 contains a clock oscillator, which is common for both driver channels; a set of comparators and flip-flops implementing the switching control; and two H-bridges with internal recirculation diodes. Voltage supply requirements are +5 V for logic and +10 to +45 V for the motor. Maximum output current is 650 mA per channel.

A special logic function is used to select slow or fast current decay in the output stage for improved high-speed microstepping. The close match between the two driver channels guarantees consistent output current ratios and motor positioning accuracy.

FAH4830 datasheet

 

Description

The FAH4830 is high-performance enhanced haptic drive for mobile phone and other hand-held devices. The haptic driver takes a single-ended PWM input signal to control a DC motor.

It can drive both Eccentric Rotating Mass (ERM) and Linear Resonant Actuator (LRA) motors. The device utilizes an external 10 kHz to 50 kHz PWM signal capable of meeting the wide range of resonant frequencies. The haptic driver takes a single-ended PWM input signal to control a DC motor.

Features

1. Direct Drive of ERM and LRA Motors

2. External PWM Input (10 kHz to 50 kHz)

3. External Motor Enable/Disable Input

4. Internal Mode-Select Register: ERM or LRA

5. Low Standby Current: <500 nA

6. Fast Wake-up Time

7. Nearly Rail-to-Rail Output Swing

 

Applications:

1. Mobile Phones

2. Handheld Devices

3. Any Key-Pad Interface
