Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductors system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore ( ), the underscore ( ) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore ( ). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild questions onsemi.com.

Factory Programmed Reset Delay: 11.5 s If the mobile device is off, holding /SR0 LOW (by pressing Factory Programmed Reset Pulse: 400 ms power-on key) for 38 ms 20% turns on the PMIC. Adjustable Reset Delay Option with External Resistor As a reset timer, it has one input and one fixed delay output. It generates a fixed delay of 11.5 s 20% by disconnecting Low < 0.2 A Typical Shutdown Current the PMIC from the battery power supply. FTL11639 does not Off Pin Turns Off Load Switch to Maintain Battery accept a new input signal for 400 ms 20% to give the PMIC Charge during Shipment and Inventory (Ready to enough time to turn off. Use Right Out of the Box) The reset delay can be customized by connecting an Typical R : 21 m (Typ.) at V =4.5 V ON BAT external resistor to the DELAY ADJ pin. Refer to Table 5. 3.8 A / 4.5 A Maximum Continuous Current As an advanced load management switch, the FTL11639 (JEDEC 2S2P, No VIA / with Thermal VIA) disconnects loads powered from the DC power rail (<6 V) with stringent off-state current targets and high load Low I Saves Power Interfacing to Low-Voltage Chips CCT capacitances (up to 200 F). The FTL11639 consists of a Input Voltage Operating Range: 1.2 V to 5.5 V slew-rate controlled low-impedance MOSFET switch (21 m typical at 4.5 V) that has exceptionally low off-state current Over-Voltage Protection: Allow Input Pins > V BAT drain (<0.2 A typical) to facilitate compliance with standby Slew Rate / Inrush Control with t : 2.7 ms (Typical) R power requirements. The slew-rate-controlled turn-on characteristic prevents inrush current and the resulting Output Capacitor Discharge Function excessive voltage drop on power rails. Zero-Second Test-Mode Enable The low I enables direct interface to lower-voltage CCT IEC61000-4-2, Level 4 compliant SYS WAKE Pin chipsets without external translation, while maintaining low power consumption. ESD Protected: - 8 kV HBM ESD (per JESD22-A114) The device is packaged in advanced, fully green, 1.31 mm - 10 kV HBM ESD (Pin to Pin, V & V ) x 1.62 mm, Wafer-Level Chip-Scale Packaging (WLCSP) BAT OUT - 2 kV CDM (per JESD22-C101) with backside laminate providing excellent thermal conductivity, small footprint, and low electrical resistance for a wide application range.
