Product details
Overview
LTC2916HDDB-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 integrated 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 supports automotive control systems requiring robust power-up/power-down reset sequencing.
For engineers reviewing the LTC2916HDDB-1#TRMPBF datasheet, LTC2916HDDB-1#TRMPBF pinout, LTC2916HDDB-1#TRMPBF application, or LTC2916HDDB-1#TRMPBF equivalent, key selection criteria include its fixed –5% tolerance, MR pin compatibility with push-button interfaces, guaranteed RST assertion down to VCC ≥ 0.8V, internal 200ms timeout option, and DFN package suitability for thermally demanding environments.
Technical Context
The LTC2916HDDB-1#TRMPBF implements a precision comparator-based monitoring architecture with three-state SEL1/SEL2 inputs selecting one of nine internal reference voltages, and a dedicated MR pin that initiates a full reset timeout cycle when asserted low. Its internal 6.2V shunt regulator enables direct operation from supplies up to 12V when paired with an external series resistor.
Glitch immunity is achieved via dual-stage filtering: a fast comparator anti-glitch circuit (tUV ≤ 150μs) rejects short transients, while the adjustable reset timeout (200ms internal or capacitor-programmable) prevents spurious toggling during supply recovery. Threshold accuracy remains ±1.5% across –40°C to 125°C without calibration.
Key Specifications

FAQ
What is the operating temperature range of the LTC2916HDDB-1#TRMPBF?
The LTC2916HDDB-1#TRMPBF is rated for operation from –40°C to 125°C, making it suitable for under-hood automotive applications and industrial environments with elevated ambient temperatures. This rating is confirmed in the Absolute Maximum Ratings table and applies to all electrical specifications unless otherwise noted.
Does the LTC2916HDDB-1#TRMPBF require external components for basic operation?
The LTC2916HDDB-1#TRMPBF requires only a 0.1μF ceramic bypass capacitor on the VCC pin for stable operation. An external pull-up resistor on the RST pin is mandatory, and a series current-limiting resistor is needed if VCC exceeds 5.7V. No external resistors are required for threshold selection or manual reset functionality.
How does the manual reset (MR) pin function on the LTC2916HDDB-1#TRMPBF?
The MR pin on the LTC2916HDDB-1#TRMPBF is an active-low input with a built-in 100kΩ pull-up to VCC, allowing direct connection to a momentary push button. When pulled low, it initiates a full reset timeout cycle regardless of VM voltage state, releasing RST after the configured timeout period (e.g., 200ms).
Can the LTC2916HDDB-1#TRMPBF monitor a 12V supply directly?
Yes - the LTC2916HDDB-1#TRMPBF includes an internal 6.2V shunt regulator on the VCC pin. To monitor a 12V supply, connect it to VCC through a series current-limiting resistor sized to keep VCC pin current ≤5mA, enabling direct high-voltage operation without external regulators.
What is the reset timeout behavior when the RT pin is left unconnected?
When the RT pin of the LTC2916HDDB-1#TRMPBF is left floating (unconnected), the device defaults to an approximate reset timeout of 400μs. For deterministic 200ms timing, tie RT directly to VCC; for adjustable timing, connect an external capacitor from RT to GND.
