Top View SOIC-8 (Package # D0008A) θJA = 172°C/W or WSON-8 (Package # NGT0008A) θJA = 39°C/W PIN DESCRIPTIONS Pin # Pin Name Pin Function 1 SW High-side driver return. Should be connected to the common node of high and low-side MOSFETs. 2 HG High-side gate drive output. Should be connected to the high-side MOSFET gate. Pulled down internally to SW with a 10K resistor to prevent spurious turn on of the high-side MOSFET when the driver is off. 3 CB Bootstrap. Accepts a bootstrap voltage for powering the high-side driver. 4 IN Accepts a PWM signal from a controller. Active High. Pulled down internally to GND with a 150K resistor to prevent spurious turn on of the high-side MOSFET when the controller is inactive. 5 LEN Low-side gate enable. Active High. Pulled down internally to GND with a 150K resistor to prevent spurious turn-on of the low-side MOSFET when the controller is inactive. 6 VCC Connect to +5V supply. 7 LG Low-side gate drive output. Should be connected to low-side MOSFET gate. Pulled down internally to GND with a 10K resistor to prevent spurious turn on of the low-side MOSFET when the driver is off. 8 GND Ground. Block Diagram 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. 2 Submit Documentation Feedback Copyright © 2004–2013, Texas Instruments Incorporated Product Folder Links: LM27222 |
