Product details
Overview
TPS3899DL10DSER from Texas Instruments is a nano-power, precision voltage supervisor with push-button monitoring capability, ±0.5% threshold accuracy, 125nA typical quiescent current, and programmable sense/reset delay via CTS/CTR pins; it operates from 0.85V to 6V supply and delivers open-drain active-low RESET output for battery-powered microcontroller reset supervision in portable electronics.
For engineers reviewing the TPS3899DL10DSER datasheet, TPS3899DL10DSER pinout, TPS3899DL10DSER application, or TPS3899DL10DSER equivalent, key selection criteria include its 0.505V adjustable threshold, 5% typical hysteresis, –40°C to +125°C operation, WSON-6 package, and dual-capacitor-programmable timing for glitch-immune rail and push-button monitoring.
Technical Context
The TPS3899DL10DSER implements a precision comparator with built-in 5% hysteresis and independent capacitor-programmable timing paths: CTS sets sense delay (assertion) from 30µs to ~6.5s, while CTR sets reset delay (deassertion) over the same range. Its SENSE pin is decoupled from VDD and supports monitoring of external rails up to 6V, independent of supply voltage.
It features functional safety documentation support, glitch immunity (10µs at 5% VIT– overdrive), and UVLO behavior with VPOR = 700mV. The open-drain RESET output requires an external pull-up and tolerates up to 6V, enabling level-shifting across mixed-voltage systems without additional logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDD Range | 0.85V to 6V - supports ultra-low-voltage MCUs and wide-input industrial rails |
| Threshold Accuracy | ±0.5% (typical) - enables reliable reset assertion within tight voltage margins |
| Quiescent Current | 125nA (typical) - extends battery life in always-on monitoring applications |
| Hysteresis | 5% (typical) - prevents chatter during slow-ramping or noisy supply transitions |
| Adjustable Threshold | 0.505V (typical) - allows precise low-voltage rail supervision (e.g., 0.6V LDO outputs) |
| Operating Temp | –40°C to +125°C - qualified for automotive under-hood and industrial edge nodes |
| Sense Delay Range | 30µs to 6.5s (via CTS capacitor) - configurable immunity to short transients or long brownouts |
| Reset Delay Range | 40µs to 6.5s (via CTR capacitor) - ensures stable power/clock settling before MCU release |
Pinout & Package
Package: 1.5mm × 1.5mm WSON-6 (DSE), moisture-sensitive level 1, no lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - CTR | Reset delay timing input | Connects to ground-referenced capacitor to set deassertion delay; internal 500kΩ pull-up enables floating default (~80µs) |
| 2 - CTS | Sense delay timing input | Connects to ground-referenced capacitor to set assertion delay; internal 500kΩ pull-up enables floating default (~50µs) |
| 3 - GND | Analog/digital ground reference | Common return path for VDD, SENSE, and RESET; must be low-impedance for noise immunity |
| 4 - VDD | Supply voltage input | Powers internal circuitry; accepts 0.85V–6V; requires local 0.1µF ceramic bypass |
| 5 - SENSE | Monitored voltage input | High-impedance (≤0.1µA leakage) input for rail or push-button signal; supports 0–6V regardless of VDD |
| 6 - RESET | Open-drain active-low output | Asserts low when SENSE < VIT–; requires external pull-up; sinks ≤2mA; compatible with 1.8V/3.3V/5V logic |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS3897DL10DSER | Fixed 1.0V threshold; identical pinout, timing, and quiescent current; lacks adjustable 0.505V option | Best for systems with stable 1.0V+ rails where fine-grained low-threshold tuning is unnecessary | Select when threshold accuracy and nano-power are critical but 0.505V adjustability is not required |
| MAX16054ASA+ | Higher 1.5µA IQ; fixed thresholds only; SO-8 package; no CTS/CTR programmability; 125°C rated | Suitable for legacy designs needing drop-in replacement in larger footprints with less stringent IQ demands | Choose only if WSON-6 size constraint is relaxed and 125nA IQ is not mandatory |
Compared with TPS3899DL10DSER, TPS3897DL10DSER offers identical form-factor and ultra-low power but sacrifices adjustable threshold flexibility, while MAX16054ASA+ trades nano-power and programmability for broader legacy compatibility and higher drive strength - making TPS3899DL10DSER optimal for space-constrained, battery-critical, and precision-tuned applications.

FAQ
What is the exact threshold voltage of TPS3899DL10DSER?
The TPS3899DL10DSER features an adjustable negative-going input threshold (VIT–) of 0.505V (typical), factory-set per the "DL10" suffix. This value is confirmed in TI's SLVSFM0C datasheet Section 5.5, with ±0.5% accuracy over –40°C to +125°C. It is distinct from fixed-threshold variants (e.g., DL08 = 0.8V) and enables supervision of sub-1V rails such as modern processor cores.
Does TPS3899DL10DSER require an external pull-up resistor on the RESET pin?
Yes, TPS3899DL10DSER uses an open-drain active-low RESET output (DL variant), so an external pull-up resistor is mandatory. The datasheet specifies RPULL-UP = 100kΩ to VDD or another logic-rail voltage up to 6V. This allows level-shifting - for example, pulling RESET to 3.3V while VDD is 1.8V - ensuring compatibility with diverse host interface voltages.
How do CTS and CTR capacitors affect timing in TPS3899DL10DSER?
In TPS3899DL10DSER, the CTS capacitor sets the sense delay (assertion time after SENSE falls below VIT–), and the CTR capacitor sets the reset delay (deassertion time after SENSE rises above VIT– + VHYS). With no capacitor, delays are ~50µs (CTS) and ~80µs (CTR); adding 1µF yields ~619ms. Equations 2 and 3 in Section 6.3.2 quantify exact values based on capacitance and internal 500kΩ pull-ups.
Can TPS3899DL10DSER monitor a voltage rail higher than its VDD supply?
Yes. The SENSE pin operates independently of VDD and accepts input voltages from 0V to 6.0V, regardless of VDD level (0.85V–6V). This allows TPS3899DL10DSER to supervise a 5V system rail while powered from a 1.8V auxiliary supply - a key feature for fault-isolated, redundant monitoring architectures in industrial and automotive applications.
Is TPS3899DL10DSER qualified for automotive applications?
TPS3899DL10DSER is specified from –40°C to +125°C and carries functional safety documentation (FIT data, safety manual), making it suitable for automotive body electronics like BCMs and infotainment power supervisors. However, it is not AEC-Q100 qualified - for ASIL-B systems requiring certified qualification, designers should consult TI's automotive-grade alternatives or perform full system-level validation per ISO 26262.
