Product details
Overview
TPS22993RLWR from Texas Instruments is a quad-channel load switch IC with integrated GPIO and I²C control, designed for power sequencing in space-constrained portable systems. It delivers 1.2A per channel, features programmable slew rate (5 options), ON-delay (4 options), and quick output discharge (4 options), and operates across 1.0V–3.6V input voltage with VBIAS support up to 17.2V - enabling use in ultrabooks, tablets, and multi-rail server subsystems.
For engineers reviewing the TPS22993RLWR datasheet, TPS22993RLWR pinout, TPS22993RLWR application, or TPS22993RLWR equivalent, key selection criteria include its dual-control mode (GPIO/I²C), ultra-low quiescent current (<9µA per channel), 15mΩ RON at 3.3V, QFN-20 RLW package (3mm × 3mm), and configurable output discharge for safe rail shutdown.
Technical Context
The TPS22993RLWR integrates four independent N-channel MOSFETs with bias-supplied gate drive via VBIAS (4.5V–17.2V), enabling low RON operation even at sub-1.2V VIN. Its dual-control architecture allows seamless transition between GPIO (ON1–ON4) and I²C (SCL/SDA + ADD1–ADD3) without glitches, supporting dynamic reconfiguration in runtime-critical systems.
Each channel includes independently programmable registers for slew rate, ON-delay, and QOD resistance - implemented via internal charge-pump and pulldown circuitry. The device uses a shared VDD (1.62V–3.6V) for logic interface and supports fast-mode plus I²C (1MHz) with open-drain SDA/SCL and 7 unique slave addresses determined by ADD1–ADD3.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range (VIN) | 1.0V to 3.6V - supports core logic rails including 1.05V, 1.2V, 1.5V, 1.8V, and 3.3V domains. |
| VBIAS Supply Range | 4.5V to 17.2V - enables optimal gate drive for low RON across wide battery configurations (2S/3S/4S Li-ion). |
| RON (Typical) | 15mΩ at VIN = 3.3V, VBIAS = 7.2V - minimizes conduction loss and thermal rise at 1.2A continuous per channel. |
| Quiescent Current | <9µA per active channel - extends battery life in always-on subsystems like sensor hubs or wake-up controllers. |
| I²C Interface Speed | Up to 1MHz (fast-mode plus) - enables high-throughput configuration of all four channels within <1ms. |
| Operating Temperature | –40°C to +85°C - qualified for industrial and consumer portable equipment environments. |
| Shutdown Current | <6µA (all channels off) - ensures negligible leakage during deep sleep or system suspend states. |
Pinout & Package
TPS22993RLWR is housed in a 20-terminal WQFN package (RLW), 3mm × 3mm × 0.75mm, 0.4mm pitch, with exposed thermal pad. Pin 13 is GND; pins 1–20 follow standard top-view numbering as defined in TI SLVSCA3A.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN1–VIN4 | Channel input supply | Independent 1.0V–3.6V inputs per channel; each powers its respective MOSFET source. |
| VOUT1–VOUT4 | Channel output | Switched outputs delivering regulated load power; internally connected to N-FET drains. |
| ON1–ON4 | GPIO enable input | Active-high digital control; hysteresis (130mV) prevents noise-induced toggling. |
| VBIAS | Bias supply | Provides gate drive voltage for all four N-FETs; decouples logic (VDD) from power-switching domain. |
| VDD | I²C/GPIO logic supply | 1.62V–3.6V supply for internal logic, SDA/SCL buffers, and ADDx address inputs. |
| SCL / SDA | I²C interface | Open-drain bus lines requiring external pull-ups to VDD; support 1MHz fast-mode plus timing. |
| ADD1–ADD3 | I²C slave address | Three binary inputs setting one of seven unique 7-bit slave addresses (0x48–0x4E). |
| GND | Power ground | Common reference for VBIAS, VINx, VOUTx, and internal circuitry; connects to exposed thermal pad. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-control mode (GPIO + I²C) | Enables hardware-safe startup via ONx pins and runtime reconfiguration via I²C without output glitches. |
| Programmable slew rate (5 options) | Controls dV/dt during turn-on to limit inrush current - critical for capacitive loads up to 1000µF. |
| Quick output discharge (4 options) | Internally discharges VOUT to GND via 110Ω–949Ω pulldown resistors, preventing floating outputs. |
| SwitchALL™ command | I²C broadcast command simultaneously enables/disables all four channels - simplifies multi-rail sequencing. |
| Low quiescent current | <17µA total for all four channels active - reduces standby power in battery-backed systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS22975RGET | Single-channel, 2A rated, no I²C, fixed 1.5ms slew rate; smaller 1.6mm × 1.6mm X2SON package. | Lacks multi-channel integration and programmability; suited only for discrete rail control where space is extreme priority. | Select when only one rail requires switching and board area is constrained below 2.5mm² per channel. |
| TPS22990RLWR | Quad-channel, identical RLW package and pinout, but lacks I²C interface and ADDx address pins; GPIO-only control. | No firmware configurability; cannot support dynamic reconfiguration or multi-device addressing on shared buses. | Select for cost-sensitive designs where I²C is unused and GPIO-only sequencing suffices - saves ~$0.12/unit at volume. |
Compared with TPS22993RLWR, the TPS22990RLWR offers identical power performance and footprint but removes I²C flexibility, while the TPS22975RGET trades channel count and programmability for ultra-compact size - making TPS22993RLWR the only option supporting both space efficiency and firmware-driven multi-rail control.

FAQ
What is the maximum continuous current rating per channel for the TPS22993RLWR?
The TPS22993RLWR supports a maximum continuous current of 1.2A per channel under recommended operating conditions (TA ≤ 85°C, proper PCB thermal design). This rating assumes adequate copper pour and thermal vias beneath the exposed pad to maintain junction temperature below 125°C.
Can the TPS22993RLWR operate with a 1.05V input voltage?
Yes, the TPS22993RLWR is fully specified down to 1.05V input voltage (VIN), with RON maintained at 15mΩ typical when VBIAS = 7.2V. This makes it suitable for modern low-voltage core domains such as LPDDR4 I/O and AI accelerator subsystems.
Does the TPS22993RLWR require external pull-up resistors on SDA and SCL lines?
Yes, the TPS22993RLWR implements open-drain SDA and SCL interfaces and requires external pull-up resistors to VDD. Recommended values range from 1kΩ to 10kΩ depending on bus capacitance and target I²C speed (up to 1MHz).
How many unique I²C addresses can be configured on the TPS22993RLWR?
The TPS22993RLWR supports seven unique 7-bit I²C slave addresses (0x48–0x4E) using the three ADD1–ADD3 pins, each configurable as high or low. All three pins tied low yields address 0x48; all three high yields 0x4E.
Is the TPS22993RLWR pin-compatible with other devices in the TPS229xx family?
No - the TPS22993RLWR has a unique 20-pin RLW footprint and pin assignment optimized for quad-channel I²C+GPIO functionality. While TPS22990RLWR shares the same package and mechanical outline, its pinout differs in ADDx and control signal placement, making it not pin-compatible.
