Functional Block Diagram. Pin Functional Description D Package (SO-8C) DRAIN (D) Pin: This pin is the power MOSFET drain connection. It provides internal EN/UV 1 8 S operating current for both start-up and steady-state operation. BP/M 2 7 S BYPASS/MULTI-FUNCTION (BP/M) Pin: 6 S This pin has multiple functions: P Package (DIP-8C) It is the connection point for an external bypass capacitor for the D 4 5 S internally generated 5.85 V supply. EN/UV 1 8 S It is a mode selector for the current limit value, depending on the value of the capacitance added. Use of a 0.1 F capacitor results BP/M 2 7 S in the standard current limit value. Use of a 1 F capacitor results Exposed Pad (On Bottom) Internally Connected to in the current limit being reduced to that of the next smaller device 6 S SOURCE Pin size. Use of a 10 F capacitor results in the current limit being K Package increased to that of the next larger device size for TNY285-290. 5 S D 4 (eSOP-12B) It provides a shutdown function. When the current into the bypass EN/UV 1 12 S pin exceeds ISD, the device latches off until the BP/M voltage drops below 4.9 V, during a power-down or, when the UV function BP/M 2 11 S is employed with external resistors connected to the BP/UV pin, by N/C 3 10 S taking the UV/EN pin current below I minus the reset hysteresis UV N/C 4 9 S (Typ. 18.75 A). This can be used to provide an output overvolt- 8 S age function with a Zener connected from the BYPASS/MULTI- FUNCTIONAL pin to a bias winding supply. D 6 7 S PI-6577-021015 Figure 4.
