Analog Devices Inc. LTC2916HTS8-1#TRMPBF

Overview

LTC2916HTS8-1#TRMPBF from Analog Devices (formerly Linear Technology) is a high-temperature voltage supervisor IC with fixed –5% tolerance, 9 selectable nominal thresholds (12V to 1.0V + ADJ), and manual reset input. It operates from 1.5V to 5.5V supply, consumes 30μA typical quiescent current, guarantees ±1.5% threshold accuracy over –40°C to 125°C, and delivers reliable reset assertion down to VCC ≥ 0.8V. It is used in automotive control systems for monitoring critical power rails under harsh thermal conditions.

For engineers reviewing the LTC2916HTS8-1#TRMPBF datasheet, LTC2916HTS8-1#TRMPBF pinout, LTC2916HTS8-1#TRMPBF application, or LTC2916HTS8-1#TRMPBF equivalent, key selection criteria include its TSOT-23-8 package, guaranteed operation at 125°C, fixed –5% tolerance, manual reset capability, internal 200ms timeout option, and compatibility with high-voltage supplies via integrated 6.2V shunt regulator.

Technical Context

The LTC2916HTS8-1#TRMPBF implements a precision comparator-based supervision architecture with three-state SEL1/SEL2 inputs selecting one of nine internal reference voltages, and an MR pin enabling push-button-initiated reset. Its internal 6.2V shunt regulator allows direct connection to supplies up to 12V when paired with a series current-limiting resistor.

Glitch immunity is achieved through dual-stage filtering: a dedicated anti-glitch circuit requiring minimum glitch duration (tUV = 10–150μs) before state change, plus a programmable reset timeout (200ms internal or capacitor-adjustable). Threshold accuracy remains ±1.5% across –40°C to 125°C, and RST output is open-drain with VOL ≤ 0.4V at 2.5mA load.

FAQ

What is the maximum supply voltage the LTC2916HTS8-1#TRMPBF can tolerate on its VCC pin?

The LTC2916HTS8-1#TRMPBF has an absolute maximum VCC rating of 5.7V when powered directly. However, its integrated 6.2V shunt regulator allows operation from higher supplies (e.g., 12V automotive battery) when a series current-limiting resistor is used to keep VCC pin current ≤5mA. Without that resistor, exceeding 5.7V risks violating terminal current limits.

Does the LTC2916HTS8-1#TRMPBF support adjustable reset timeout, and how is it configured?

Yes, the LTC2916HTS8-1#TRMPBF supports adjustable reset timeout via the RT pin. Connecting an external capacitor (CRT) from RT to GND sets tRST ≈ 9ms/nF (e.g., 2.2nF yields ~20ms). Leaving RT floating gives ~400μs; tying RT to VCC selects the fixed 200ms internal timeout. This flexibility enables precise power-up sequencing across diverse system architectures.

How does the manual reset (MR) function work on the LTC2916HTS8-1#TRMPBF?

The MR pin on the LTC2916HTS8-1#TRMPBF is active-low with an internal 100kΩ pull-up to VCC. Asserting MR low while RST is high initiates a full reset cycle: RST goes low immediately and remains low for the full timeout period (200ms or capacitor-adjusted), then releases. This enables simple pushbutton integration without external pull-ups or debounce circuitry.

Can the LTC2916HTS8-1#TRMPBF monitor a 1.0V supply, and what is the guaranteed accuracy?

Yes, the LTC2916HTS8-1#TRMPBF supports 1.0V nominal monitoring (–5% = 0.95V trip point) via SEL1=GND and SEL2=Open. Threshold accuracy is guaranteed at ±1.5% of nominal voltage over –40°C to 125°C, meaning the actual trip point falls within 0.935V to 0.965V across temperature - sufficient for modern low-voltage SoC power rails.

Is the LTC2916HTS8-1#TRMPBF pin-compatible with other members of the LTC2915/LTC2916 family?

Yes, the LTC2916HTS8-1#TRMPBF shares identical pinout and package (TSOT-23-8) with all LTC2915/LTC2916 variants in TS8 packaging, including LTC2915CTS8-1#TRPBF and LTC2916ITS8-1#TRPBF. Pin functions (VM, SEL1, MR, GND, RST, RT, SEL2, VCC) are fully consistent - enabling drop-in replacement within same temperature grade and functional variant.
