Product details
Overview
SIP32104DB-T1-GE1 from Vishay Siliconix is a bidirectional load switch IC with active-low enable, 6.5 mΩ typical on-resistance at 3.3 V, 7 A continuous current rating, and operation across 2.3 V to 5.5 V input voltage range - used for battery-disconnect control in portable medical systems and multi-source power routing where reverse-current blocking and slew-rate-controlled turn-on are required.
For engineers reviewing the SIP32104DB-T1-GE1 datasheet, SIP32104DB-T1-GE1 pinout, SIP32104DB-T1-GE1 application, or SIP32104DB-T1-GE1 equivalent, this page delivers verified package mapping, validated EN logic behavior, confirmed bidirectional conduction capability, and real-world timing parameters including 0.8 ms turn-on delay and 1 ms rise time under standard test conditions.
Technical Context
The SIP32104DB-T1-GE1 implements a true bidirectional FET switch with symmetrical A/B port conduction and integrated slew-rate gate drive logic that limits inrush current during capacitive load switching. Its internal bias circuit supports direct interface with low-voltage GPIO without external level shifting.
Unlike SiP32101/SiP32103, the SIP32104DB-T1-GE1 features no integrated EN pull resistor - requiring external pull-down or pull-up per system logic requirements - while maintaining identical 6.5 mΩ RDS(on), 7 A current capability, and -40 °C to +85 °C operating temperature range.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SiP32101DB-T1-GE1 | Includes integrated 500 kΩ EN pull-down resistor; otherwise identical RDS(on), timing, and thermal specs | Reduces external component count in systems requiring default-OFF behavior with no pull-up needed | Select when simplified enable interface is prioritized over logic flexibility |
| TPS22975DQNR | Single-directional only; 4.7 mΩ RDS(on); 6 A rating; requires external reverse-blocking diode for bidirectional use | Lacks native reverse-current blocking - unsuitable for battery-isolation without added components | Select only for unidirectional paths where cost-per-amp is critical and reverse flow is impossible |
Compared with SiP32101DB-T1-GE1, SIP32104DB-T1-GE1 offers greater enable logic flexibility but requires an external resistor; compared with TPS22975DQNR, it delivers true bidirectionality and reverse blocking in a single device, eliminating layout overhead and failure modes from discrete diodes.

FAQ
What is the enable logic configuration of SIP32104DB-T1-GE1?
The SIP32104DB-T1-GE1 features an active-low enable (/EN) with no internal pull resistor - meaning external pull-down or pull-up must be provided based on system-level logic requirements. This differs from SiP32101DB-T1-GE1 (integrated pull-down) and SiP32103DB-T1-GE1 (integrated pull-up), giving designers full control over default state and leakage optimization. The /EN pin asserts switch conduction when voltage is ≤ 0.4 V and disables conduction when ≥ 1.4 V.
Does SIP32104DB-T1-GE1 support reverse current blocking?
Yes, SIP32104DB-T1-GE1 provides true reverse current blocking in both directions when disabled - preventing current flow from Port A to Port B or Port B to Port A. This is achieved via internal FET architecture and is confirmed in the functional description, absolute maximum ratings, and typical characteristics (Fig. 12). It is essential for battery isolation safety in portable medical and consumer devices.
What is the maximum continuous current rating for SIP32104DB-T1-GE1?
The SIP32104DB-T1-GE1 supports 7 A continuous bidirectional current at both Port A and Port B under specified thermal conditions (TA = 70 °C, 2 oz copper, 4-layer PCB). Derating applies above 70 °C at 13.7 mW/°C. This rating is validated across the full -40 °C to +85 °C operating temperature range and is consistent across all SiP3210x variants.
How does the slew-rate control in SIP32104DB-T1-GE1 improve system reliability?
The built-in slew-rate control in SIP32104DB-T1-GE1 limits output rise time to 1 ms (typ.), reducing inrush current into large load capacitors and preventing supply rail collapse, voltage droop-induced resets, and EMI emissions. This feature is especially valuable in smartphones and medical monitors where 100–1000 μF bulk capacitance is common and uncontrolled turn-on could disrupt sensitive analog circuits or communication interfaces.
Is SIP32104DB-T1-GE1 compatible with 1.8 V GPIO control signals?
Yes, SIP32104DB-T1-GE1 is compatible with 1.8 V GPIO control signals because its /EN pin has a logic-low threshold of ≤ 0.4 V and logic-high threshold of ≥ 1.4 V - ensuring reliable recognition of 1.8 V logic levels. No level shifter is required, and the 110 nA quiescent current remains unchanged regardless of input voltage within the 2.3 V–5.5 V supply range.
