Description
The SLG47105-E provides a small, low-power component for commonly used mixed-signal and bridge functions. The user creates their circuit design by programming the one-time programmable (OTP) non-volatile memory (NVM) to configure the interconnect logic, the IO pins, the high-voltage pins, and the macrocells of the SLG47105-E. Configurable PWM macrocells in combination with special high-voltage outputs will be useful for motor drive or load drive applications. High-voltage pins allow for the design of smart level translators or for driving the high-voltage high-current load.
