Simplified Schematic Block Diagram IN THERMAL SHUTDOWN UVLO MOSFET DRIVER WITH CURRENT LIMIT AUTO LOW POWER MODE INTEGRATED SOFT−START ACTIVE DISCHARGE EN BANDGAP REFERENCE ENABLE LOGIC EN OUT GND Table 1. PIN FUNCTION DESCRIPTION Pin No. XDFN6 Pin No. TSOP−5 Pin Name Description 1 5 OUT Regulated output voltage pin. A small 1 mF ceramic capacitor is needed from this pin to ground to assure stability. 2 4 N/C Not connected. 3 2 GND Power supply ground. Connected to the die through the lead frame. Soldered to the copper plane allows for effective heat dissipation. 4 3 EN Enable pin. Driving EN over 0.9 V turns on the regulator. Driving EN below 0.4 V puts the regu- lator into shutdown mode. 5 N/C Not connected. This pin can be tied to ground to improve thermal dissipation. 6 1 IN Input pin. A small capacitor is needed from this pin to ground to assure stability. Table 2. ABSOLUTE MAXIMUM RATINGS Rating Symbol Value Unit Input Voltage (Note 1) VIN −0.3 V to 6 V V Output Voltage VOUT −0.3 V to VIN + 0.3 V V Enable Input VEN −0.3 V to VIN + 0.3 V V Output Short Circuit Duration tSC Indefinite s Maximum Junction Temperature TJ(MAX) 150 °C Storage Temperature TSTG −55 to 150 °C ESD Capability, Human Body Model (Note 2) ESDHBM 2000 V ESD Capability, Machine Model (Note 2) ESDMM 200 V Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality should not be assumed, damage may occur and reliability may be affected. 1. Refer to ELECTRICAL CHARACTERISTICS and APPLICATION INFORMATION for Safe Operating Area. 2. This device series incorporates ESD protection and is tested by the following methods: ESD Human Body Model tested per AEC−Q100−002 (EIA/JESD22−A114) ESD Machine Model tested per AEC−Q100−003 (EIA/JESD22−A115) Latchup Current Maximum Rating tested per JEDEC standard: JESD78. |
