Datasheet 2ch IPS (Intelligent Power Switch) BDS2EJAAGUL General Description Key Specifications VCC Input voltage range: 3.0V to 3.6V BDS2EJAAGUL is an intelligent power switch IC Switch input voltage range: 0.9V to 3.6V (IPS) that has two built-in N-channel MOSFETs Enable input voltage range: -0.3V to 5.5V capable of carrying 1A current. This switch IC Switch output voltage range: 0V to 3.6V operates from low input voltages from 0.9V to Maximum output current: 1A (Max) 3.6V and exhibits a typical on-resistance of 45 Standby current: 0 A (Typ) m. Built-in safety features include soft-start, Operating temperature range: -40C to +100C over current protection with fold back current limiting, under voltage lockout, thermal shut Package(s) W(Typ) x D(Typ) x H(Max) down and reverse current protection when VCSP50L1 1.95mm x 1.00mm x 0.55mm power is switched off. BDS2EJAAGUL is available in a space-saving VCSP50L1 package and uses an internal N-channel MOSFET for discharging output capacitance. Features Dual N-MOS FET high side switch (Typ 45m). Built-in soft start circuit. Built-in over current protection circuit (OCP). Built-in thermal shut down circuit (TSD). Built-in N-channel MOSFET to discharge output capacitance Reverse-current protection. Input sequence free.
