Battery tracking protection Programmable tracking Protection
B61089QDR, d ual port negative voltage tracking SLIC protector
Description

This component is designed to protect two different SLIC (Subscriber Line Interface Card) tip/ring pairs with independent voltage tracking for each pair. This B61089QDR will protect the SLIC interface against lightning induced surge and power fault events. It contains fast switching crowbarring structures for negative events and a simple fast switching diode structure for positive events. It is compatible with the Basic Levels of ITU K.20, K.21, and K.45. For compliance with the Enhanced Levels of ITU, TIA GR-1089, an additional series resistor in the tip and ring leads may be required. Agency Approvals

The SLIC chipset voltage reference may change as the on-hook/off-hook line condition changes. Therefore, this component is referenced to the - VBAT so that its negative protection threshold follows this changing reference voltage level. This B610989QDR utilizes a transistor gain network so that a low 5 mA current level will activate the thyristor based portion of this protector component during negative events. This also allows an easier turn on during slow rising power fault events. For all positive disturbances, the fast switching diode connected to earth reference will provide the needed protection. Features Dual port negative voltage tracking programmable component High holding current 150 mA min Specified 2/10 limiting voltage Integrated diodes for positive surge protection ESD Immunity(HBM): JESD22 Class 3B, 8KV MSL: Level 1 - unlimited RoHS compliant and lead-free

- Initially the protector must be in thermal equilibrium with TJ=25C. The surge may be repeated after the device returns to its initial conditions. - These non-repetitive rated currents are peak values for either polarity. The rated current values may be applied to any cathode-anode terminal pair. Additionally, all cathode-anode terminal pairs may have their rated current values applied simultaneously (in this case the anode terminal current will be four times the rated current value of an individual terminal pair).
