Product details
Overview
TPS3613-01DGSRG4 from Texas Instruments is a precision battery-supervisory IC with backup-battery switchover, dual reset outputs (active-high and active-low), chip-enable gating, and adjustable supply-voltage monitoring for CMOS RAM data retention. It features 40 µA max VDD supply current, 100 nA max battery supply current, 100-ms fixed power-on reset delay, and operates from −40°C to +85°C in portable battery-powered equipment.
For engineers reviewing the TPS3613-01DGSRG4 datasheet, TPS3613-01DGSRG4 pinout, TPS3613-01DGSRG4 application, or TPS3613-01DGSRG4 equivalent, this device is selected for low-power system supervision where reliable RAM backup, fast CE signal gating (<3 ns), and precise 1.15 V threshold sensing are required in space-constrained designs.
Technical Context
The TPS3613-01DGSRG4 integrates a precision voltage reference, comparator-based SENSE input with 12 mV hysteresis, internal 100-ms reset timer, and dual-path power switching: a 1-Ω (max) PMOS switch from VDD to VOUT and an 8–15 Ω NMOS switch from VBAT to VOUT. Its switchover logic ensures VBAT powers RAM only when VDD falls below VIT and VBAT > VDD - preventing reverse current and enabling use of higher-voltage lithium cells (e.g., 3.6 V).
Chip-enable gating uses a series transmission gate between CEIN and CEOUT, disabled during reset assertion to isolate memory buses; propagation delay is as low as 1 ns at VDD = 5 V. Manual reset (MR) input provides asynchronous reset override with sub-µs response time, and both RESET outputs drive CMOS loads with VOH ≥ VDD − 0.4 V and VOL ≤ 0.4 V under full load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current (IDD) | 40 µA max - enables multi-year operation on coin-cell backup without compromising supervision accuracy. |
| Battery Supply Current (IBAT) | 100 nA max - minimizes self-discharge of backup batteries during long-term storage or standby. |
| Reset Threshold (VIT) | 1.15 V ±20 mV - precisely triggers reset before microcontroller brownout, ensuring deterministic boot sequence. |
| Reset Delay Time | Fixed 100 ms - guarantees sufficient hold time for processor initialization and peripheral stabilization. |
| CE Propagation Delay | ≤3 ns at VDD = 5 V - supports high-speed memory interfaces without timing violation in fast-access systems. |
| VDD-to-VOUT RDS(on) | ≤1 Ω - limits voltage drop to <200 mV at 200 mA, preserving supply integrity for downstream RAM. |
| Operating Temperature | −40°C to +85°C - qualified for industrial and automotive cabin applications requiring extended thermal range. |
Pinout & Package
TPS3613-01DGSRG4 is housed in a 10-pin VSSOP (DGS) package, 3.0 mm × 3.0 mm × 1.1 mm, with exposed pad for thermal performance and RoHS-compliant NiPdAu lead finish. Pin 1 is marked with a dot; device orientation follows JEDEC MO-187 BA standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT | Power output | Delivers regulated supply to CMOS RAM; switches automatically between VDD and VBAT based on threshold comparison. |
| VDD | Main supply input | Primary system rail (1.65–5.5 V); powers internal circuitry and sources VOUT when valid. |
| GND | Ground reference | Common return path for all analog and digital functions; must be low-impedance for stable threshold detection. |
| MR | Manual reset input | Active-low asynchronous reset trigger; pulls both RESET outputs active when asserted. |
| CEIN | Chip-enable input | Accepts processor CE signal; gated internally to prevent memory corruption during undervoltage. |
| CEOUT | Chip-enable output | Passes CEIN when reset inactive; pulled to VOUT via internal pullup when reset active. |
| RESET | Active-high reset output | Drives microcontroller reset pin high during fault; VOH ≥ VDD − 0.4 V ensures TTL/CMOS compatibility. |
| RESET | Active-low reset output | Provides complementary reset signal for legacy or dual-input logic; VOL ≤ 0.4 V at 3 mA load. |
| SENSE | Adjustable threshold input | Monitors scaled VDD via external resistor divider; sets VIT = 1.15 V with 12 mV hysteresis for noise immunity. |
| VBAT | Backup battery input | Accepts 1.5–5.5 V backup source; connects to VOUT only when VDD < VIT and VBAT > VDD, avoiding backfeed. |
Key Features
| Feature | Design Value |
|---|---|
| Backup-battery switchover | Automatic VDD/VBAT selection with 55 mV VBSW hysteresis prevents oscillation during recovery and supports >VDD battery voltages (e.g., 3.6 V Li). |
| Dual reset outputs | Simultaneous active-high and active-low RESET signals eliminate need for external inverters in mixed-logic systems. |
| Chip-enable gating | Sub-3 ns CEIN→CEOUT delay and automatic disable during reset prevent spurious memory writes during power collapse. |
| Low-quiescent-current supervision | 40 µA IDD and 100 nA IBAT enable decade-scale battery life in always-on monitoring applications. |
| Adjustable VDD monitoring | SENSE pin accepts resistor-divider feedback to set custom reset thresholds across 1.13–1.17 V range with ±0.5% accuracy. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar supervisory circuit applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS3619-01DGSR | Fixed 3.08 V reset threshold (non-adjustable); identical pinout, package, and CE gating specs. | Suitable for systems with fixed 3.3 V rails where SENSE divider is unnecessary; lacks VDD monitoring flexibility. | Select when threshold is known and stable; eliminates external resistors but forfeits adjustability. |
| MAX6361KA29+T | 2.93 V fixed threshold; 12 µA quiescent current; no VBAT switchover or CE gating functionality. | Basic reset-only function; requires external circuitry for battery backup and memory isolation. | Choose for ultra-low-power reset-only needs where backup switchover and CE control are handled elsewhere. |
Compared with TPS3613-01DGSRG4, TPS3619-01DGSR trades adjustability for simplified design in fixed-rail systems, while MAX6361KA29+T reduces supply current by 70% but omits critical RAM-protection features like VBAT switchover and CE gating - making it unsuitable for data-retention-critical applications.

FAQ
What is the exact reset threshold voltage of the TPS3613-01DGSRG4?
The TPS3613-01DGSRG4 has a nominal negative-going input threshold voltage (VIT) of 1.15 V, with a guaranteed range of 1.13 V to 1.17 V across temperature and process variation. This threshold applies to the SENSE pin and is used to determine when VDD has fallen below the valid operating level, triggering reset assertion. The device also includes 12 mV of hysteresis to prevent chatter near the threshold.
Does the TPS3613-01DGSRG4 support backup battery voltages higher than the main supply?
Yes, the TPS3613-01DGSRG4 explicitly supports VBAT > VDD - for example, a 3.6 V lithium coin cell can back up a 3.3 V or lower main rail. The internal switchover logic connects VBAT to VOUT only when VDD falls below VIT and VBAT exceeds VDD, preventing reverse current and enabling safe use of higher-voltage backup sources without external diodes or FETs.
How does the chip-enable gating function work in the TPS3613-01DGSRG4?
The TPS3613-01DGSRG4 gates the CEIN signal through an internal transmission gate to CEOUT. During normal operation (reset inactive), CEIN passes directly to CEOUT with ≤3 ns propagation delay. When reset is asserted, the gate disables, placing CEIN in high-impedance and pulling CEOUT to VOUT via an internal active pullup - blocking erroneous memory accesses during undervoltage conditions.
What package type and dimensions does the TPS3613-01DGSRG4 use?
The TPS3613-01DGSRG4 uses a 10-pin VSSOP (DGS) package measuring 3.0 mm × 3.0 mm × 1.1 mm maximum height, with 0.5 mm pin pitch and exposed thermal pad. It is RoHS-compliant with NiPdAu lead finish and rated MSL Level-1 (unlimited floor life at ≤30°C/60% RH). Tape-and-reel packaging is supplied in 2500-unit reels.
Can the TPS3613-01DGSRG4 be used in automotive applications?
Yes, the TPS3613-01DGSRG4 is characterized for operation from −40°C to +85°C and meets automotive ambient requirements for cabin-located electronics such as infotainment head units and telematics modules. Its 1.15 V reset threshold, low IBAT (100 nA), and robust VDD/VBAT switchover make it suitable for retaining RAM contents during stop-start cycles and ignition-off periods.
