Fixed the BQ24074RGTT terminal metadata from the TI datasheet.
Updated all 17 terminals with datasheet-derived Pin Type and Pin Description, including standard pin types for IN, OUT, BAT, VSS, EP, open-drain status outputs, and programming/control pins. Verification passed, and the terminal-related part review checks returned no reported issues.
I’ll switch the symbol metadata to parametric style, assign each terminal to datasheet-based functional sections, and verify the resulting symbol properties.
I assigned each pin to a datasheet-based section and orientation: power-path pins to Power, VSS/EP to Ground, TS to Analog, and control/programming/status pins to Control. I also set terminal order by datasheet pin number and verified the updates; terminal/parametric review checks returned no reported issues.
Stand-alone single-cell linear battery charger with power path
BQ24074RGTT is a highly integrated standalone linear charger and power-path management IC from Texas Instruments designed for single-cell Li-Ion/Li-Polymer battery-powered portable devices. It supports charging directly from USB ports or external adapters while simultaneously powering the system load through integrated Dynamic Power Path Management (DPPM). The device is commonly used in portable electronics, IoT devices, wireless accessories, handheld medical devices, and battery-powered embedded systems.
