DRV8835HB01B
Description
The DRV8835 provides an integrated motor driver solution for cameras, consumer products, toys, and other low-voltage or battery-powered motion control applications. It features two H-bridge drivers capable of driving two DC motors or one stepper motor. The output driver block for each consists of N-channel power MOSFETs configured as an H-bridge. An internal charge pump generates gate drive voltages, and it includes protection features for overcurrent, short circuit, undervoltage lockout, and overtemperature.
The module can be used to control a stepper motor.
Features
- Dual H-Bridge Motor Driver capable of driving:
- Two DC Motors or
- One Stepper Motor
- Low MOSFET ON-Resistance: HS + LS 305 mΩ
- 1.5-A Maximum Drive Current per H-Bridge
- Bridges can be configured in parallel for up to 3-A Drive Current
- Separate motor (0-V to 11-V) and logic (2-V to 7-V) supply pins
- Flexible PWM or PHASE/ENABLE Interface
- Low-Power Sleep Mode with 95-nA Maximum Supply Current
Applications
Ideal for battery-powered applications such as:
- Cameras
- DSLR Lenses
- Consumer Products
- Toys
- Robotics
- Medical Devices
Setup and Configuration
- Power Supply:
- Ensure that the VCC is connected to a 2 V to 7 V supply.
- Connect VM to a supply voltage between 0 V and 11 V depending on the required motor voltage.
- Input Configuration:
- The default mode (IN/IN) is selected by setting MODE to low or leaving it unconnected.
- Switch to PHASE/ENABLE mode by setting MODE to high.
- Sleep Mode:
- Enter low-power sleep mode by setting all inputs to low (0 V).
