BD2244G-M and BD2245G-M 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 AEC-Q100 Qualified Adjustable Current Limit Threshold: 200mA to 1.7A Built-in Low On-Resistance (Typ 100m Ω) N-channel MOSFET Built-in Soft-Start Circuit Output Discharge Function Open-Drain Fault Flag Output Thermal Shutdown Under-Voltage Lockout Reverse Current Protection when Power Switch Off Control Input Logic Active-High: BD2244G-M Active-Low: BD2245G-M Applications Car accessory Key Specifications Input Voltage Range: 2.8V to 5.5V On Resistance: (IN=5V) 100m Ω(Typ) Current Limit Threshold: 0.2A to 1.7A adjustable Standby Current: 0.01 μA (Typ) Operating Temperature Range: -40°C to +85°C Package W(Typ) x D(Typ) x H(Max) Typical Application Circuit CL 120 μF CIN 1 μF IN GND EN OUT /OC 5V (Typ) + - RLIM ILIM 3.3V 10k Ω to 100k Ω 10 μF Lineup Output Load Current Adjustable Current Limit Threshold Channel Control input logic Package Orderable Part Number Max 1.5A 200mA to 1.7A 1ch High SSOP6 Reel of 3000 BD2244G – MGTR 1.5A 200mA to 1.7A 1ch Low SSOP6 Reel of 3000 BD2245G – MGTR SSOP6 2.90mm x 2.80mm x 1.25mm Figure 1.
