Frequently Asked Questions
Q1: What is the meaning of suffix‑OVY22 for GL3520‑OVY22?
A: OV stands for commercial temperature grade and package option. VY means integrated LDO and fast‑charge function. 22 is standard power version, different from OVY10(low‑voltage) and OVY21(lite version).
Q2: Can GL3520‑OVY22 work without external EEPROM?
A: Yes. It uses internal ROM default parameters. EEPROM is only needed when you require custom VID / PID.
Q3: What is the difference between GL3520‑OVY22, OVY10 and OVY21?
A: OVY22: full‑feature standard version with complete LDO & charging function. OVY10: low‑voltage variant for special power supply. OVY21: lightweight version with partial functions cut. They are not fully pin‑to‑pin compatible.
Q4: What are alternative replacement chips for GL3520‑OVY22?
A: Reference alternatives: GL3523, VL817. Note: They differ in power consumption, charging capability and pin assignment. Not direct drop‑in replacement, schematic re‑check is required.
Q5: Does GL3520‑OVY22 support charging when host is suspended?
A: Yes. It supports CDP / DCP mode and can still supply charging current for mobile devices under host suspend status.
Q6: Can GL3520‑OVY22 be used for industrial temperature products?
A: No. This is commercial grade 0~+70℃. Do not use for wide‑temperature industrial scenarios.
Q7: Where can I get schematic reference and PCB layout suggestion?
A: Submit your requirement through inquiry form, we will send reference design documents for evaluation.
