Short-circuit protection is integrated on the output, so the charge path shuts down before the battery or PCB trace can fault — one less external fuse or PTC to budget. Housed in a 20-ball UCSP75M2 (2.2x2.2 mm) — a fine-pitch wafer-level CSP. The 0.5 mm ball pitch demands a controlled impedance layout and a stencil aperture that matches the ball diameter for reliable solder joint formation. ## Temperature grade and supply rail Operating temperature spans -30°C to 85°C ambient — enough margin for a device that sits near a warm battery pack in a sealed enclosure, but not rated for under-hood automotive or extended 105°C ambient. Maximum supply voltage is 5.5V, which aligns with USB VBUS (5V nominal). The charger can run directly from a USB port or a 5V wall adapter without an external LDO.","metaTitle":"ROHM BD8665GW-E2 Li-Ion Battery Charger, 8.4V, USB","metaDescription":"ROHM BD8665GW-E2 Li-Ion battery charger IC, 8.4V pack voltage, USB interface, short-circuit protection, active production.
