LP2985

The DRV8835 evaluation module (EVM) demonstrates the capabilities and performance of the DRV8835 motor driver from Texas Instruments. User can control the DRV8835 with an external microcontroller via signal header connectors or use on-board switches for stand-alone operation.

• 2.0 to 11V supply voltage range.
• Split Vm/Vcc supply isolates motor voltage from logic supply.
• Access to output signals through Kelvin contact for easy evaluation.
• Jumper for switching between MCU or manual operation.
• LP2985-50 5V regulator supplies high logic level and Vcc in manual operation mode, no (...)

• 3.3 V to 11 V Operating Supply Voltage Range
• Supports Up to 1 A Maximum Drive Current
• Separate 3.3 V Logic Supply
• Simple Control Interface with MSP430G2131
• USB Connector for 5 V Motor Supply

The LDC1314KEYPAD evaluation module implements a 16 snap dome button keypad using only one LDC1314 to multiplex all 16 buttons.

This design uses the LDC1314 but can also be replicated with the LDC1312, LDC1612 and LDC1614.
