Manufacturer

Texas Instruments (Luminary Micro/Texas Instruments). Y-IC is a quality distributor for Texas Instruments, and we will provide you with the best products and services.

Detailed Description

Precision voltage supervisor/reset IC with a 3.0 V factory-set threshold (G30) in a compact SOT-23-6 (DBV) package. Monitors supply rails, asserts a clean active-low reset on undervoltage, offers an adjustable reset delay using a single external capacitor, and includes a manual reset input. Designed for reliable power-on reset and brownout protection in embedded systems.

Key Features

Fixed 3.0 V threshold (G30 version) for common logic rails

Accurate trip point with built-in hysteresis for stable operation

Adjustable reset timeout using an external timing capacitor (CT)

Manual Reset (MR) pin for user or system-triggered resets

Sense pin to monitor VDD or an alternate supply rail

Active-low CMOS reset output with fast response

Low supply current for battery-friendly designs

Wide operating range compatible with typical MCU/FPGA power rails

Small SOT-23-6 footprint, simple layout, easy design-in

Robust brownout detection and power-on sequencing

Key Advantages

Protects processors and digital logic from unstable or low supply voltage

Programmable delay enables easy power sequencing without firmware

High accuracy reduces false resets and improves system uptime

Minimal external components — often just one timing capacitor

Tiny package saves PCB space and supports dense layouts

Low quiescent current extends battery life in portable devices

Flexible monitoring of primary or secondary rails with a single IC

Packaging

Type: Surface-mount device (SMD), SOT-23-6

Manufacturer package code: DBV (TI)

Material: Molded epoxy body, copper leadframe with standard lead finish

Size: Ultra-compact SOT-23-6 outline (low profile, space-saving)

Pin configuration (6 pins): VDD, GND, RESET, SENSE, CT (delay capacitor), MR (manual reset)

Pin pitch: Fine-pitch SOT-23 standard for automated SMT assembly

Thermal characteristics: Standard SOT-23 thermal behavior; very low self-heating due to low current; follow TI layout guidance for best thermal performance
