4 / 37 page LM25037, LM25037-Q1 SNVS572E – JULY 2008 – REVISED JANUARY 2016 www.ti.com Pin Functions (continued) PIN I/O DESCRIPTION APPLICATION INFORMATION NO. NAME Locally decouple with a 0.1 µF or greater capacitor. Maximum output 15 REF O Output of a 5-V reference current is 10 mA (typical). Input to the VCC Start-up regulator. Operating input range is 5.5 V to 16 VIN I Input voltage source 75 V. For power sources outside of this range, the LM25037 can be biased directly at VCC by an external regulator. 6 Specifications 6.1 Absolute Maximum Ratings over operating junction temperature range (unless otherwise noted) (1) (2) MIN MAX UNIT VIN to GND –0.3 76 V VCC, RAMP , OUTA, OUTB to GND –0.3 16 V CS to GND –0.3 1 V UVLO, FB, RT2, RT1, SS, REF to GND –0.3 7 V COMP, RES(3) Junction temperature 150 °C Storage temperature –65 150 °C (1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) If Military/Aerospace specified devices are required, contact the Texas Instruments Sales Office/ Distributors for availability and specifications. (3) COMP, RES are output pins. As such, TI does not recommend connecting external power sources to these pins. 6.2 ESD Ratings: LM25037 VALUE UNIT Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) ±2000 V(ESD) Electrostatic discharge V Charged-device model (CDM), per JEDEC specification JESD22- ±750 C101(2) (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. (2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. 6.3 ESD Ratings: LM25037-Q1 VALUE UNIT Human-body model (HBM), per AEC Q100-002(1) ±2000 Electrostatic V(ESD) All pins ±750 V discharge Charged-device model (CDM), per AEC Q100-011 Corner pins (1, 8, 9, 16) ±750 (1) AEC Q100-002 indicates that HBM stressing shall be in accordance with the ANSI/ESDA/JEDEC JS-001 specification. 6.4 Recommended Operating Conditions over operating junction temperature range (unless otherwise noted) MIN NOM MAX UNIT VIN voltage 5.5 75 V External voltage applied to VCC 8 14 V Operating junction temperature −40 125 °C 4 Submit Documentation Feedback Copyright © 2008–2016, Texas Instruments Incorporated Product Folder Links: LM25037 LM25037-Q1 |
