SLAU915 May 2024 ULC1001
The ULC1001-DRV2911EVM consists of ULC1001-Q1, a configurable PWM modulator, and DRV2911-Q1, a PWM-input driver. The ULC1001 device hosts integrated lens cleaning algorithms with an on-chip low-latency DSP, measures load current and voltage using integrated amplifiers, and drives the PWM inputs of the DRV2911. The DRV2911 integrates two H-bridges for driving piezo based Lens Cover Systems up to 40V absolute maximum capability. DRV2911 integrates a power management LDO (3.3V / 30mA) that can be used to power external circuits, like ULC1001. The EVM also includes a MSP430 micro-controller which can control ULC1001 via four programmable push buttons. Various power devices are also implemented to supply the system.
