Introduction
TPS1HTC30AQPWPRQ1 - Automotive-Grade High-Side Intelligent Power Switch
An automotive-grade, high-side intelligent power switch designed for harsh automotive environments, compliant with AEC-Q100 Grade 1 standards.
Core Functions
High-Side Power Switching
Acts as a high-side switch to control the on/off state of automotive electrical loads, supporting both DC and pulse-width modulation (PWM) load control with low on-resistance for minimal power loss.
Comprehensive Protection Mechanisms
- Overcurrent Protection (OCP): Automatically limits output current or shuts down the device when the load current exceeds the threshold, preventing damage from short circuits.
- Overtemperature Protection (OTP): Triggers thermal shutdown when the junction temperature exceeds the safe limit, with automatic recovery after cooling.
- Overvoltage Protection (OVP): Clamps the input voltage to avoid damage from transient voltage spikes (e.g., load dump in automotive systems).
- Reverse Polarity Protection: Blocks current flow when the power supply is reversed, safeguarding the device and connected loads.
Diagnostic & Feedback Features
Provides a diagnostic output pin to transmit fault status (e.g., overcurrent, overtemperature) to the host MCU, enabling real-time system monitoring and fault handling.
Automotive-Grade Robustness
Operates over a wide temperature range (-40°C to +125°C) and withstands automotive electrical transients (ISO 7637 compliance), ensuring stable performance in harsh conditions.
Typical Applications
Automotive Body Electronics
- Control of exterior lighting (headlights, taillights, turn signals) and interior lighting (dome lights, reading lights)
- Power management for door locks, window regulators, and seat adjustment systems
- Control of windshield wipers and washers
Automotive Powertrain & Chassis Systems
- Switching for fuel injectors and ignition coil drivers (low-power auxiliary circuits)
- Control of cooling fans and coolant pumps in engine thermal management systems
- Power distribution for ABS (Anti-lock Braking System) and ESC (Electronic Stability Control) auxiliary components
Industrial & Commercial Vehicle Systems
- Power switching for commercial vehicle auxiliary equipment (air compressors, refrigeration units)
- Control of industrial automation actuators and solenoid valves in harsh environments
