TSZ02201-0E3E0H300280-1-2 9.JUN.2014 Rev.004 www.rohm.com 1 Channel Compact High Side Switch ICs 1ch Adjustable Current Limit High Side Switch ICs BD2222G BD2242G BD2243G Description BD2222G, BD2242G and BD2243G are low on-resistance N-channel MOSFET high-side power switches, optimized for Universal Serial Bus (USB) applications. These devices are equipped with the function of over-current detection, thermal shutdown, under-voltage lockout and soft-start. Moreover, the range of Current limit threshold can be adjusted from 0.2A to 1.7A by changing the external resistance. Features Adjustable Current Limit Threshold: 200mA to 1.7A Low On-Resistance (Typ 89mΩ) N-channel MOSFET Built-in Soft-Start Circuit Output Discharge Function BD2242G, BD2243G Open-Drain Fault Flag Output Thermal Shutdown Under-Voltage Lockout Reverse Current Protection when Power Switch Off Control Input Logic Active-High Active-High: BD2222G, BD2242G Active-Low: BD2243G Applications USB hub in consumer appliances, PC, PC peripheral equipment and so forth Key Specifications Input Voltage Range: 2.8V to 5.5V On Resistance: (IN=5V) 89mΩ(Typ) Current Limit Threshold: 0.2A to 1.7A adjustable Standby Current: 0.01µA (Typ) Operating Temperature Range: -40°C to +85°C Package W(Typ) D(Typ) H (Max) SSOP6 2.90mm x 2.80mm x 1.25mm Typical Application Circuit CL 120µF CIN 1µF IN GND EN OUT /OC 5V (Typ) + - RLIM ILIM 3.3V 10k Ω to 100k Ω 10µF Lineup Output Load Current Adjustable Current Limit Threshold Channel Control input logic Output Discharge function Package Orderable Part Number Max 1.5A 200mA to 1.7A 1ch High No SSOP6 Reel of 3000 BD2222G – GTR 1.5A 200mA to 1.7A 1ch High Yes SSOP6 Reel of 3000 BD2242G – GTR 1.5A 200mA to 1.7A 1ch Low Yes SSOP6 Reel of 3000 BD2243G – GTR SSOP6 Figure 1.
