| MIC2596/2597 Micrel MIC2596/2597 Dual Channel Negative Voltage Hot Swap Controllers Final Information The MIC2596 and MIC2597 are dual channel negative voltage hot swap controllers designed to facilitate safe PC board insertion into and removal from live backplanes. To minimize external components, each channel of the MIC2596/MIC2597 has an integrated high voltage power MOSFET. Built-in current sensing in each channel provides inrush current limiting, by regulating the channel’s output current to a usersettable maximum. Current sensing also provides programmable overcurrent and open-load detection. A channel will be turned off if it experiences overload or no-load conditions lasting longer than programmable intervals. Foldback current limiting holds power dissipation of the internal MOSFETs at safe levels during overloads, and very fast shutdown response to faults ensures protection for both system power supplies and the load. The MIC2596 will automatically attempt to restart into an overcurrent fault until the fault is cleared, while the MIC2597 will latch the output in the off state until it is reset by external action. A logic-compatible signal is provided on each channel to indicate overcurrent or undercurrent fault conditions. • Allows safe hot-swap in systems • Operates to • Programmable inrush current limiting • Two thermally isolated channels • Overcurrent fault sensing and protection • Nuisance trip prevention circuitry • Open-load detection • Logic compatible Enable and Fault signals • Separate analog and logic ground pins support large system ground differentials ±8V • Central Office Switching • Power Distribution +3.3V VCC FAULT#_CH1 FAULT#_CH2 CONTROLLER ON/OFF_CH1 ON/OFF_CH2 VDDA VCLAMP OUT1 ILIMIT 2 FAULT#1 FAULT#2 CGATE1 17 ON1 10 ON2 MIC2596 C1 R1 15 VDDL OUT2 12 CTIMER1 CGATE2 14 C2 C3 8 CTIMER2 COL1 ILIMIT2 9 C4 COL2 System-Controlled Hot Swap VOUT1 CL VOUT2 Micrel, Inc. • 1849 Fortune Drive • San Jose, CA 95131 • USA • tel + 1 408 944-0800 • fax + 1 408 944-0970 • April 2001 MIC2596/2597 MIC2596/2597 Ordering Information Part Number MIC2596-1BTS MIC2596-2BTS MIC2597-1BTS MIC2597-2BTS MIC2596-1BTSE ON Signal Active-High Active-Low Active-High Active-Low Active-High MIC2596-2BTSE Active-Low MIC2597-1BTSE Active-High MIC2597-2BTSE Active-Low Circuit Breaker Function Auto-Retry Auto-Retry Latched Off Latched Off Auto-Retry Auto-Retry Latched Off Latched Off Package 20 pin TSSOP 20 pin TSSOP 20 pin TSSOP 20 pin TSSOP 20 pin Exposed Pad TSSOP 20 pin Exposed Pad TSSOP 20 pin Exposed Pad TSSOP 20 pin Exposed Pad TSSOP Micrel MIC2596/2597 April 2001 MIC2596/2597 Pin Configuration ON1 1 ILIMIT1 2 CTIMER1 3 COL1 4 VCLAMP 5 VDD/VDDA* 6 COL2 7 CTIMER2 8 ILIMIT2 9 ON2 10 20 FAULT#1 19 OUT1 18 N/C 17 CGATE1 16 VEE 15 VDDL* 14 CGATE2 13 N/C 12 OUT2 11 FAULT#2 20-Pin TSSOP Micrel Pin Descriptions Pin Number 20, 11 Pin Name FAULT1#/FAULT2# 1, 10 ON1/ON2 CTIMER1/CTIMER2 ILIMIT1/ILIMIT2 19, 12 6 OUT1/OUT2 VDDA VCLAMP COL1/COL2 |
