Datasheet Load Switch ICs 0.2A, 0.5A Current Load Switch ICs for Portable Equipment BD2202G BD2206G General Description Key Specifications BD2202G and BD2206G are high-side switch ICs using a Input Voltage Range: 2.7V to 3.6V single N-Channel MOSFET with low on resistance. These ON-Resistance: 150m(Typ) ICs have over-current protection and this is triggered Operating Load Current: when the ov-ercurrent condition exceeds the BD2202G 0.2A over-current shutdown time. After triggering the BD2206G 0.5A over-current protection, the switch will be latched off Over-Current Threshold: until enable is reset. BD2202G 0. 2 5A (Min), 1.0A (Max) Moreover, soft start, under-voltage lockout, and thermal BD2206G 0 .8 A (Min), 1.6A (Max) shutdown are integrated. These ICs are used in power Standby Current: 0.01A (Typ) supply lines of memory card slots. Operating Temperature Range: -25C to +85C Features Package W(Typ) D(Typ) H (Max) Single Low ON-Resistance (Typ= 150m) N-Channel MOSFET Control Input Logic: Active-High Soft Start Function Over-Current Protection Circuit Thermal Shutdown Circuit Under-Voltage Lockout Applications Memory Card Slots, Digital Still Cameras, Cell Phones, Notebook PCs SSOP5 2.90mm x 2.80mm x 1.25mm Typical Application Circuit OUT IN C V IN IN C R OUT OUT GND EN OFF ON Lineup Control Input Over-Current Threshold Package Orderable Part Number Logic Min Typ Max 0.25A - 1.0A High SSOP5 Reel of 3000 BD2202G-TR 0.8A - 1.6A High SSOP5 Reel of 3000 BD2206G-TR Product structureSilicon monolithic integrated circuit This product has not designed protection against radioactive rays www.rohm.com TSZ02201-0E3E0H300180-1-2 2013 ROHM Co., Ltd.
