Pin Descriptions Pin Name Description 1 RSP Positive current sense input 2 VCC Positive supply voltage 3 NC No Connection – Not internally Connected. 4 GND Ground 5 VOUT Output 6 NC or REFA LMP8480: No Connection LMP8481: Reference Voltage “B” Input 7 NC or REFB LMP8480: No Connection LMP8481: Reference Voltage “A” Input 8 RSN Negative current sense input These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. Absolute Maximum Ratings (1) Over operating free-air temperature range (unless otherwise noted). LMP8480, LMP8481 UNIT Supply Voltage (VCC to GND) -0.3 to +85 V RSP or RSN to GND -0.3 to +85 V VOUT to GND -0.3 to the lesser of (VCC + 0.3) or +20 V Other VREF pin tied to ground -0.3 to +12 V VREF Pins (LMP8481 Only) Applied to both VREF Pins tied together -0.3 to +6 V Differential Input Voltage ±85 V Current into output pin ±20 (2) mA Current into any other pins ±5 (2) mA Operating Temperature –40 to +125 °C Storage Temperature -65° to +150 °C Junction Temperature +150 °C MSOP-8 185 °C/W Package Thermal Resistance ( θJA) LLP-8 70 °C/W Human Body Model (HBM) 2000 V ESD Ratings Charged Device Model (CDM) 750 V (1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics Tables. (2) When the input voltage (VIN) at any pin exceeds power supplies (VIN < GND or VIN > VS ), the current at that pin must not exceed 5mA, and the voltage (VIN) has to be within the Absolute Maximum Rating for that pin. The 20mA package input current rating limits the number of pins that can safely exceed the power supplies with current flow to four pins. 4 Submit Documentation Feedback Copyright © 2012, Texas Instruments Incorporated Product Folder Links: LMP8480 LMP8481 |
