Product details
Overview
SIP32102DB-T5-GE1 from Vishay Siliconix is a bidirectional load switch IC designed for battery-disconnect and multi-source power switching in portable electronics. It features 6.5 mΩ typical on-resistance at 3.3 V, 7 A continuous current capability, and operates across 2.3 V to 5.5 V input voltage range. Its active-high enable with integrated pull-down resistor enables direct low-voltage GPIO control in space-constrained battery-powered systems.
For engineers reviewing the SIP32102DB-T5-GE1 datasheet, SIP32102DB-T5-GE1 pinout, SIP32102DB-T5-GE1 application, or SIP32102DB-T5-GE1 equivalent, key selection criteria include bidirectional conduction symmetry, slew-rate-controlled turn-on for in-rush suppression, ultra-low quiescent current (110 nA), WCSP12 package footprint compatibility, and EN logic polarity matching system control architecture.
Technical Context
The SIP32102DB-T5-GE1 implements a true bidirectional FET switch with identical A and B port characteristics, enabling equal current flow in either direction without polarity dependency. Its internal slew-rate gate drive logic limits di/dt during turn-on, reducing peak in-rush into large load capacitors up to 0.1 μF.
It integrates an active-high enable input with a 500 kΩ (typ.) internal pull-down resistor, eliminating external bias components. The device uses internal level-shifting circuitry to ensure reliable EN signal interpretation across its full 2.3–5.5 V operating range, with VIH ≥ 1.4 V and VIL ≤ 0.4 V thresholds.
Key Specifications

Key Features
| Feature | Design Value |
|---|---|
| Bidirectional conduction | Identical RDS(on), reverse blocking, and current rating on PA and PB ports - eliminates directional wiring constraints in battery/system interconnects |

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 | Active-low enable with internal pull-down; otherwise identical RDS(on), current rating, and package | Requires inverted control signal; suitable where host MCU GPIO defaults high or open-drain | Select when system control logic is naturally active-low or shares EN net with other active-low peripherals |
| SIP32103DB-T1-GE1 | Active-low enable with internal 500 kΩ pull-up; same electrical specs and WCSP12 package | EN floats high at power-up, defaulting switch ON unless actively pulled low | Choose for fail-safe "power-on" behavior where default conduction is required before firmware initialization |
Compared with SIP32102DB-T5-GE1, SIP32101DB-T1-GE1 requires signal inversion for enable control, while SIP32103DB-T1-GE1 defaults ON at power-up - both retain identical 6.5 mΩ RDS(on), 7 A rating, and WCSP12 footprint, enabling layout reuse with only EN routing changes.

FAQ
What is the maximum continuous current rating for SIP32102DB-T5-GE1?
The SIP32102DB-T5-GE1 supports 7 A continuous current in either direction between Port A and Port B. This rating is validated over the full −40 °C to +85 °C operating temperature range with proper PCB thermal design per Vishay's recommended 1" × 1", 2 oz. copper, 4-layer layout. Derating applies above 70 °C ambient per the 13.7 mW/°C thermal resistance specification.
Does SIP32102DB-T5-GE1 support reverse current blocking when disabled?
Yes, SIP32102DB-T5-GE1 provides reverse current blocking on both Port A and Port B when disabled. When the EN pin is low, the internal FET is fully off and isolates the ports, preventing current flow in either direction - a critical feature for battery isolation and fault containment in portable systems using SIP32102DB-T5-GE1.
What is the function of the A4 bump on SIP32102DB-T5-GE1?
The A4 bump on SIP32102DB-T5-GE1 is the /EN (enable) input terminal, configured for active-high logic. It accepts 1.4 V minimum high-level input and includes an integrated 500 kΩ pull-down resistor, allowing direct connection to standard GPIO outputs without external bias components - a key design simplification in the SIP32102DB-T5-GE1 implementation.
Can SIP32102DB-T5-GE1 operate from a 2.5 V supply?
Yes, SIP32102DB-T5-GE1 operates across 2.3 V to 5.5 V input voltage range. At 2.5 V, it maintains full 7 A current capability and 6.5 mΩ typical on-resistance (measured at 3.3 V), with RDS(on) rising to ≤8 mΩ per datasheet specifications - making SIP32102DB-T5-GE1 suitable for single-cell Li-ion systems operating down to 2.7 V nominal.
Is SIP32102DB-T5-GE1 pin-compatible with SIP32101DB-T1-GE1?
No - while SIP32102DB-T5-GE1 and SIP32101DB-T1-GE1 share identical WCSP12 pinout, bump assignment, and package dimensions, their EN logic polarity differs: SIP32102DB-T5-GE1 uses active-high enable, whereas SIP32101DB-T1-GE1 uses active-low. Therefore, direct replacement requires signal inversion or firmware update to maintain correct switch behavior in the SIP32102DB-T5-GE1 application.
