NAME DESCRIPTION 1 PWM Pulse-width modulation input. If not used, connect to I. 2 ST Status output. Open-collector output. Connect to an external pullup resistor (RPULLUP ≥ 4.7 kΩ). 3 GND Ground 4 REF Reference input. Connect to a shunt resistor. 5 D Status delay. To set status reaction delay, connect to GND with a capacitor. If no delay is needed, leave open. 6 Q Output 7 NC No internal connection 8 I Input. Connect directly to GND as close as possible to the device with a 100-nF ceramic capacitor. Thermal The thermal pad must be soldered directly to the PCB. It may be connected to ground or left floating. Pad FUNCTIONAL BLOCK DIAGRAM 2 Submit Documentation Feedback Copyright © 2008–2009, Texas Instruments Incorporated |
