Suffix X indicates that the part is available in 2.5k units on Tape and Reel. * Current is sampled over a fixed interval. The average current during this interval is indicated by the duty cycle of the PWM output during next interval. ‡ The Package code M08A is internal to National Semiconductor and indicates an 8-lead surface mount package, SO-8. Pin Description (High-Side, LM3812) Pin Name Function 1 SENSE+, V DD High side of internal current sense, also supply voltage. 2 SENSE− Low side of internal current sense. 3 FLTR+ Filter input — provides anti-aliasing for delta sigma modulator. 4 FLTR− Filter input. 5SD Shutdown pin. Connected to V DD through a pull up resistor for normal operation. When low, the IC goes into a low current mode (typically 3 µA). 6 PWM PWM output indicates the current magnitude and direction. 7 GND Ground 8 GND Ground Pin Description (Low-Side, LM3813) Pin Name Function 1 SENSE+, GND High side of internal current sense, also ground. 2 SENSE− Low side of internal current sense. 3 FLTR+ Filter input – provides anti-aliasing for delta sigma modulator. 4 FLTR− Filter input. 5SD Shutdown pin. Connected to V DD through a pull up resistor for normal operation. When low, the IC goes into a low current mode (typically 3 µA). 6 PWM PWM output indicates the current magnitude and direction. 7 GND Ground 8V DD V DD (supply) www.national.com 2 |
