Краткое описание:
Bidirectional DC powerline comms mgmt IC, 3.4–5.5V, 166.7kbps, 9‑WLP
Дополнительная информация
Universal bidirectional DC powerline communication (PLC) management IC with I2C control, configurable master/slave operation, up to 166.7 kbps bit rate, automatic slave detection, and integrated switches supporting up to 1.2 A charge current. Includes slave‑mode LDO (up to 200 mA), programmable PLC sink current, and compact 9‑bump WLP (1.358 mm × 1.358 mm, 0.4 mm pitch) for space‑constrained wearable and hearable designs.
