Technical Specifications
Technical Summary
This document covers the Quanta Computer Inc. BL5 Touch Pad Board, designated as board number A-0122, revision B2A, dated October 25, 2007. The board integrates a power button circuit using a NTC033-XB1G-X160T tactile switch (SW1) and a BL123-04R-TAND connector (CN1) for interface integration. An LED indicator (LED1) is specified as a Liteon LTW-C191DS5 for power/standby status. ESD protection is provided by a BZ5V6 zener diode (D1). The board includes EMI filtering capacitors C1, C2, and C3, each rated at 100pF/50V. The design incorporates a 390-ohm pull-up resistor (R1) on the power button signal line. The document revision history indicates multiple circuit and BOM modifications, including changes to the switch, connector, and ESD protection components for SMT and integration improvements.
