Full title and description

Road vehicles — Intelligent power switches — Part 2: Low-side intelligent power switch. This International Standard specifies minimum requirements for 12 V and 24 V body-system low-side intelligent power switches (LSIPS) intended primarily for automotive applications (e.g., lamps, motors, relays).

Abstract

Specifies the minimum requirements (functioning, electrical characteristics, protection and diagnostic features, and test methods) for low-side intelligent power switches for road-vehicle body systems operating on 12 V and 24 V nominal supply voltages. The standard defines expected behaviour, protection functions and the tests used to verify compliance.

• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 43.040.10 (Electrical and electronic equipment for road vehicles).
• Edition / version: Edition 1 (1996).
• Number of pages: 24 pages.

Scope

Defines minimum functional and electrical requirements, protection and diagnostic features, and associated test methods for low-side intelligent power switches used in 12 V and 24 V vehicle body systems. It is intended for switches placed between the load and vehicle negative (battery minus) and covers typical automotive load types and environmental/electrical conditions relevant to road vehicles.

Key topics and requirements

• Definition and functional description of low-side intelligent power switches (LSIPS): self-protection, status reporting and positive logic inputs.
• Electrical specifications for 12 V and 24 V systems, including on-resistance, voltage/current ratings and variations with supply voltage.
• Protection features: overcurrent/short-circuit protection, thermal protection, and automatic recovery behaviour.
• Diagnostic and status signalling requirements (functional status information and failure reporting).
• Test methods and normative tests to verify functioning, electrical characteristics and protection behaviour.
• Packaging, marking and information to be supplied with the component for correct application in vehicle systems.

Typical use and users

Used by automotive component manufacturers (power-switch/IC suppliers), vehicle OEM electrical design teams, test laboratories and certification bodies to design, specify and verify low-side intelligent power switches for vehicle body applications (lamps, motors, relays, actuators). The standard helps ensure interoperability, safety and predictable protection/diagnostic behaviour in 12 V and 24 V vehicle electrical systems.

Related standards

ISO 10483 is a multi-part series; Part 1 covers high-side intelligent power switches (ISO 10483-1). Other related vehicle electrical standards include standards addressing electrical transient/disturbance testing (for example ISO 7637 series) and component-level circuit-breaker/circuit-protection standards referenced within vehicle electrical equipment ICS listings.

A: It covers functional behaviour, electrical characteristics for 12 V and 24 V systems, required protection features (overcurrent, thermal, short-circuit behaviour), diagnostic/status reporting and the normative tests used to verify these requirements.

Q: Who typically uses it?

A: Automotive power-switch/semiconductor manufacturers, vehicle OEM electrical designers, test laboratories and conformity assessment bodies use it to design, specify and verify LSIPS for automotive applications.

Q: Is it current or superseded?

A: The published edition is ISO 10483-2:1996 (Edition 1).
