Key Features
- 27 selectable factory-preset voltage thresholds eliminate external resistor dividers for fast design-in
- Integrated watchdog timer detects CPU lockup and triggers system reset without additional supervisor ICs
- Single-channel supervision in a compact 10-pin MSOP package suits space-constrained embedded designs
Applications
The LTC2917HMS-A1#PBF is designed for microprocessor and DSP power-on reset, brownout detection, and watchdog supervision in telecommunications, industrial control, and automotive electronics. Its 27 selectable thresholds cover common supply rails from 1.0V to 5.0V, making it easy to drop into battery-powered IoT edge nodes, server management controllers, and safety-critical embedded systems where single-rail voltage monitoring and CPU watchdog are both required.

Frequently Asked Questions
How do the 27 selectable thresholds in the LTC2917HMS-A1#PBF simplify voltage supervisor design?
The LTC2917HMS-A1#PBF stores 27 factory-preset voltage thresholds selectable via a 5-pin input code, covering common supply rails typically ranging from 1.0V to 5.0V. This eliminates the need for an external resistor divider network, reducing BOM by 2 components and removing tolerance errors that external resistors would introduce into the threshold accuracy.
What role does the integrated watchdog timer play in the LTC2917HMS-A1#PBF, and what systems benefit most?
The watchdog timer in the LTC2917HMS-A1#PBF monitors a periodic kick signal from the host CPU; if the CPU fails to toggle the watchdog within the programmed timeout window, the IC asserts a reset to recover the system. This is critical in unattended industrial controllers, telecom line cards, and embedded medical monitors where software lockup would otherwise require a manual power cycle.
What package does the LTC2917HMS-A1#PBF use, and how does it affect PCB layout for high-density boards?
The LTC2917HMS-A1#PBF is supplied in a 10-pin MSOP (S-PDSO-G10) package with a body footprint of approximately 3mm x 3mm, significantly smaller than an equivalent DIP-8 supervisor. This compact SMT package allows placement directly adjacent to the monitored supply decoupling capacitors, keeping the sense trace short and reducing susceptibility to noise on the monitored rail in high-density PCB designs.
Is the LTC2917HMS-A1#PBF suitable for automotive or industrial applications requiring extended temperature operation?
The LTC2917HMS-A1#PBF is rated for the H-grade industrial temperature range, supporting operation from -40°C to +85°C, which covers most industrial and automotive-adjacent applications. The plastic MSOP package with epoxy encapsulation is qualified per JESD-609 e3 for moisture sensitivity, making it compatible with standard lead-free SMT reflow processes at peak temperatures of 260°C.
