2 / 11 page LM34902 SNVS804B – MAY 2012 – REVISED APRIL 2013 www.ti.com Connection Diagram Figure 1. Top View 6-Bump Thin DSBGA Package See Package Number YFQ PIN DESCRIPTION Pin Name Function Number Power input of the PFET switch. It also provides power to the entire IC. Connect to the voltage rail that the VCC A1 accessory device is expected to work off. GND B1 Common Ground (device substrate). POK C1 Open-drain PFET status indicator. When the PFET is off, this pin floats. When PFET is on, it is grounded. ACC_DET C2 Pull this pin low to tell the IC that the downstream accessory device is plugged in. When this pin is low, the PFET will be turned off and POK will be open-drained. Current limit circuitry will also ENABLE B2 be disabled. The IC will be in a low-power state. This pin should be held low until VCC is established to ensure proper initial state of internal logic. When ENABLE is high, the PFET switch will be allowed to turn on. ACC_PWR A2 Power output terminal of the PFET switch. Connect to input rail of accessory device. Truth Table Input Output Current Limit TJ Limit PFET Switch ENABLE ACC_DET 2.8V < VCC < 5.3V POK Detected Exceeded Status 0 x No No Yes Open Open Drain x 1 No No Yes Open Open Drain 0 to 1 0 No No Yes On Grounded 0 to 1 0 Yes No Yes Current Limited Grounded x x x Yes 2.2V < VCC < 5.3V Open Open Drain 0 x x No 2.2V < VCC < 2.8V Open Open Drain Note: "x" stands for "don't care". 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) VCC -0.3V to 6V ENABLE, POK, ACC_DET, ACC_PWR(2) -0.3V to 6V Junction Temperature (TJ) +150°C Storage Temperature Range −65°C to +150°C ESD Susceptibility, Human Body Model(3) 2kV (1) Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which operation of the device is ensured. Operating Ratings do not imply ensured performance limits. For ensured performance limits and associated test conditions, see the Electrical Characteristics table. (2) The voltages on these pins should never exceed VCC+0.3V. (3) The human body model is a 100pF capacitor discharged through a 1.5 k Ω resistor into each pin. Test method is per JESD-22-A114. 2 Submit Documentation Feedback Copyright © 2012–2013, Texas Instruments Incorporated Product Folder Links: LM34902 |
