Overview

ISO 10483-2:1996 - Road vehicles - Intelligent power switches - Part 2: Low-side intelligent power switch (LSIPS) specifies the minimum requirements for 12 V and 24 V body‑system low‑side intelligent power switches used in road vehicles. Intended primarily for automotive loads such as lamps, motors and relays, the standard defines functional behavior, electrical requirements, test methods and packaging for semiconductor LSIPS devices.

Key topics and technical requirements

• Functions: Defines two main LSIPS functions - the switching function and overcurrent/thermal self‑protection with a single Status bit for diagnostics.
• Device variants: Battery‑connected control supply (LSIPS‑B) and regulated control supply (LSIPS‑R).
• Status and input behavior:
  • Positive logic input: logic “1” → on (except in overload); logic “0” or floating → off.
  • Status output indicates open‑load or overload (logic “0”), otherwise logic “1”; Status is an open‑drain/open‑collector type.
• Electrical limits:
  • Supply/clamping: load pin clamping voltage > 40 V (12 V systems) or > 60 V (24 V systems); clamping threshold > 22 V (40 V).
  • Case temperature: device must be functional across −40 °C to 125 °C (parameters may vary).
  • Supply quiescent current:
