概述

Description

TPS16530PWPR is a Texas Instruments voltage supervisor/reset IC. It monitors a system supply and, when the supply comes up or drops out of spec, it generates a reset signal to a microcontroller or other digital logic to ensure reliable startup and operation. The device typically provides a defined reset timeout, power-on reset behavior, and may include a manual reset input and optional watchdog/enable features, depending on the variant. The PWPR suffix indicates a specific package variant used for this device (small, surface-mount package). Applications include microcontroller supervision in embedded systems, automotive, and industrial electronics. For exact voltage thresholds, timing, and pinout, consult the TPS16530PWPR datasheet and product page.

Features

Here are the key features of the TPS16530PWPR (microprocessor reset/monitor supervisor):
- Single-supply voltage supervisor with Power-On Reset (POR) for MCU startup
- Monitors Vcc and asserts reset if supply is out of range or unstable
- Manual reset input (reset push/button) with debounced/reset control
- Watchdog input (WDI) to detect software hangs; watchdog timeout triggers reset
- Reset output (RST#) is active-low (deterministic, glitch-filtered)
- Defined reset width and timing to guarantee proper MCU reset on power-up
- Low quiescent current suitable for battery-powered apps
- Small 8-pin PWPR package (compact footprint)
- Wide operating temperature range (typical -40°C to 125°C) and broad supply range (per datasheet)
Note: For exact voltage thresholds, timing values, and pin behavior, please consult the TPS16530PWPR datasheet.

Package

TPS16530PWPR comes in an 8-pin VSSOP package (VSSOP-8, 3×3 mm).

Pinout

- Pin count: 8 pins (PWPR package)
- Function: Voltage supervisor/reset generator for microcontrollers; monitors Vcc and asserts a reset output when the supply is out of spec (undervoltage or during power-up/power-down).

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: An American multinational technology company that designs and manufactures semiconductors and related components (notably analog, mixed-signal, and embedded processing ICs).

Application

TPS16530PWPR is TI’s high-side power switch with built-in protection (current limit, overcurrent/short-circuit protection, undervoltage lockout) for safe rail switching. Applications include automotive body electronics, industrial controls, consumer electronics, telecom/network power rails, and battery-powered devices. Typical use cases: hot-swap and power‑up sequencing for MPUs/GPUs/ASICs, FPGAs, memory and sensors, and protection of loads from shorts while providing controlled on/off behavior.

Equivalent

There isn’t an exact one-to-one equivalent for TPS16530PWPR; it’s a TI voltage supervisor/reset monitor. For substitutes, match the same voltage range, reset threshold, delay, and output type. Closest options: TI TPS3800/TPS383x family; Microchip MCP130/MCP131; Maxim MAX809/MAX810; Analog Devices ADM803/ADM809. Verify package and fault behavior.
